Bang Rak is one of Bangkok's oldest districts — a tangle of Silom skyscrapers, Charoen Krung shophouses, and sois (alleyways) lined with food carts. And where there's food carts in Bangkok, there's som tam. The rhythmic pok pok of mortar and pestle is the district's unofficial soundtrack.
But here's the thing Reddit will tell you about som tam: there is no single "best." Every soi has its own vendor, every vendor has her own hand, and every plate is pounded to your exact specifications. What we can tell you is where the locals queue, which Isaan joints punch above their weight, and which fancy spots are actually worth the markup.
We scoured Reddit threads from r/Bangkok, r/Thailand, r/ThailandTourism, r/BangkokEats, and r/ThaiFood to build this guide. These are the spots that long-term Bangkok residents and Isaan food obsessives come back to again and again.
📊 How we built this list
We analyzed 80+ Reddit posts and 400+ comments across r/Bangkok, r/Thailand, r/ThailandTourism, r/BangkokEats, r/ThaiFood, and r/BangkokTravelGuide — spanning 2020 to 2026. Spots were ranked by how frequently they were recommended by independent users, with long-term resident picks weighted more heavily than tourist posts. Every spot on this list was mentioned in at least 2 separate threads by different people.
What to order: Som Tam Pu Pla Ra (papaya salad with salted crab and fermented fish) if you're feeling brave. Otherwise, Som Tam Thai with salted duck egg (Tam Thai Khai Khem) is the crowd-pleaser. Pair it with gai yang (grilled chicken) and sticky rice.
"Som tam jay so ftw. Love their chicken more than the som tam honestly."

"I strongly recommend you to try Som Tam Jay So, one of the best street food experiences I've ever had in Bangkok."

"Arrive before 11:30 to beat the lunch rush. Don't wear white; papaya salad stains."
— r/BangkokTravelGuide · posted 2025
tabiji verdict: The undisputed queen of som tam in Silom. Jay So herself has been pounding papaya on this soi for years, and the lunch-hour queue of Thai office workers is all the validation you need. The som tam is fiery, the gai yang is exceptional, and at ฿40–80 per dish it's absurdly cheap. Go before 11:30 or expect to wait. Open daily until about 4:30 PM — no dinner service.
What to order: Their extensive som tam menu goes well beyond papaya — try the Thai-style with peanuts, or go for the corn (khao phot) or cucumber (dtaeng) variations. The larb and nam tok are solid sides.
"The som tam in particular. Definitely a place I will return to. Very good, spicy food for a reasonable price. Probably my favourite restaurant in Silom."
— TripAdvisor (via r/Bangkok) · posted 2024
"Soi convent som tam."
— r/Bangkok · 9 upvotes
tabiji verdict: A Bang Rak institution. The shophouse atmosphere is no-frills but comfortable, the menu is enormous, and the Convent Road location means you're eating alongside Silom office workers who know exactly what to order. Great for anyone who wants the street som tam experience with actual chairs and a roof. Lunch gets packed — come early or late.
What to order: The tum kha moo (som tam with pork leg) is their signature twist. For a classic, the som tam with salted egg and crispy pork is excellent. Good beer selection too.
"Somtum Der in Si Lom has a large selection of good somtum and variations."
— r/Bangkok · 4 upvotes
"For mid range: Somtum Der, one of my favorite places in Bangkok."
— r/ThailandTourism · posted 2025
tabiji verdict: The polished, air-conditioned answer to "I want great som tam but I also want a proper restaurant." Their New York outpost once had a Michelin star; the Bangkok original has a Bib Gourmand. The som tam is entry-level Isaan done with care — not the cheapest, not the most hardcore, but reliably good with creative twists. The bright, airy room feels like a modern fast-casual joint. A safe bet for som tam newcomers.
What to order: With 29+ types of som tam, the menu is overwhelming. Start with the salted duck egg version (tam khai khem), or go for the kanom jeen noodle combo. Their grilled meats and laab are worthy sides.
"Baan Somtam is nice as well!"
— r/Bangkok · 3 upvotes
"Baan Somtam is awesome. My girlfriend says it's like her mom's cooking."
— r/Bangkok · 2 upvotes
"Baan Somtum for mid range. Thipsamai for Pad Thai in the lower range."
— r/ThailandTourism · posted 2025
tabiji verdict: If som tam is your love language, Baan Somtum is your paradise. Twenty-nine varieties means they take green papaya salad as seriously as a wine bar takes grapes. The Sathon branch right on the edge of Bang Rak is the best — the pok-pok chorus hits you before you even walk in. Spice levels are no joke. Bring sticky rice.
💰 ฿60–150
📍 Multiple locations (Ari, Central Chidlom, etc.)
📌 Google Maps →
What to order: They specialize in pla ra (fermented fish sauce) — go for any som tam with pla ra for the authentic Isaan experience. Their multiple varieties of fermented fish are the star. The strawberry som tam at Central Chidlom is a surprisingly good wildcard.
"Phed Phed isn't that spicy, what they specialize in is pla ra. They have many types of it available. It's a good place to try."
— r/Bangkok · 3 upvotes
"PhedPhed is the bomb!"
— r/Bangkok · 2 upvotes
"for me the best somtum is Phed-Phed in central chidlom... I'm Thai, love somtum and I eat all over Bangkok. I know I can't believe somtum in a shopping mall tastes better than on the street... especially strawberry-somtum is the best from here"
— r/Bangkok · 1 upvote
tabiji verdict: The name means "spicy spicy" but the real draw is their obsessive collection of pla ra varieties. This is where Bangkok's Isaan food nerds go to geek out over fermented fish sauce the way wine people talk about terroir. Multiple locations means you can find one near you. The Central Chidlom branch inside a shopping mall shouldn't be this good — but Thai locals swear by it.
What to order: Watch for the vendors with the biggest mortar and pestle and the longest queue. Ask for Som Tam Thai with 2 chilies to start. The beauty is customization — tell them exactly what you want and they'll pound it fresh.
"Haha there is no 'best' somtum. On each soi you'll find multiple versions all made slightly differently, just find one you like."
— r/Bangkok · 65 upvotes
"Grab driver last year told me when I asked him this same question — 'any corner, any food cart.'"
— r/Bangkok · 24 upvotes
tabiji verdict: This isn't a single vendor — it's a philosophy. Convent Road fills up at lunchtime with som tam carts serving the Silom office crowd, and the most upvoted Reddit advice about som tam is literally "any corner, any food cart." The beauty of Bangkok's som tam culture is that a random ฿30 street plate can be transcendent. Look for the cart with the queue and the ancient grandma with the clean equipment. You'll pay a third of what the sit-down places charge.
What to order: Whatever the lady is pounding. Suan Plu Soi 8 has several food vendors — the som tam stall opposite the police station on the main road is the one people talk about. Get sticky rice and any grilled meat on offer.
"Head towards Suan Plu Soi 8. There's lots of great, old school street food along the lane. The best of the best is a little Som Tam spot, opposite the police station on the main road."
— r/Bangkok · 2 upvotes
tabiji verdict: This is the kind of rec you only get from someone who lives in the neighborhood. Suan Plu is a quiet residential soi just south of Bang Rak proper, lined with old-school street food that hasn't been gentrified yet. The som tam stall opposite the police station is the real deal — no English menu, no frills, just an Isaan auntie making incredible papaya salad for ฿30. Worth the detour if you want the authentic experience tourists never find.
What to order: The som tam is solid, but this is a full Thai kitchen — their massaman curry and boiled bitter gourd with minced pork soup are the real stars. Get som tam as your starter, then go deep on the curries.
"Krua Aroy-Aroy, 3, opposite Wat Khaek, 1 Pan Rd, Yan Nawa, Bang Rak. Proper local Thai food — try the Massaman Curry and boiled bitter gourd with mince pork soup. Cheap as well, worth a try if you want to eat like a local."
— r/Bangkok · 3 upvotes
tabiji verdict: Not a som tam specialist — it's a proper neighborhood Thai restaurant where the som tam happens to be genuinely good alongside everything else. The kind of place where a Redditor drops a Google Maps pin with "proper local Thai food" and three upvotes. Bang Rak locals love it. Come for the papaya salad, stay for the massaman curry.
What to order: The Isaan holy trinity: fried chicken + som tam + sticky rice. Their birds are fried to a crispy-skinned finish, and the som tam is the perfect spicy-sour counterpoint. This is a combo meal, not a som tam destination — but it's one of Bangkok's best combos.
"The Som Tam at Polo Fried Chicken is really good. And you can have fried chicken at the same time!"
— r/Bangkok · 1 upvote
tabiji verdict: You don't come here just for the som tam — you come for the holy trinity. Crispy fried chicken, punchy green papaya salad, and sticky rice, eaten together, is one of Thailand's greatest meals. Soi Polo has been doing this combination to perfection for decades. It's a short walk from Bang Rak proper, near Lumphini Park. The chicken is the headliner, but the som tam plays a crucial supporting role.
What to order: The laab (minced meat salad) is the signature, but the som tam — both Bangkok and Isaan styles — is solid. Get the salt-crusted fish and gai yang to share. They're open absurdly late, making this a go-to after-midnight Isaan spot.
"Must go: soei, som tam jay so, crispy pork alley, kor panich sticky rice."
— r/ThailandTourism · 7 upvotes
tabiji verdict: The som tam here won't top a list of Bangkok's absolute best — but the total Isaan experience might. Laab Ubon is sprawling, raucous, and open until 4 AM. Dua Lipa ate here on her Bangkok tour stop. The som tam is one dish in a massive spread of Ubon-style Isaan food that's meant to be shared around a table with cold beers. Come for the vibe, the variety, and the late hours.
What to order: Their apple som tam is the wildcard — green papaya swapped for crisp apple, pounded with the same dressing. Also try the traditional papaya version and the mango variety. And yes, look for the car covered in giant plastic lizards outside.
"I went to Somtum Dontree (literally, 'musical somtum') the other day and it was amazing. They make varieties of somtum outside the traditional papaya, too — had somtum made with apples and it was delicious. The owner, for some reason, has stuck massive plastic lizards all around his car."
— r/Thailand · 1 upvote
tabiji verdict: "Musical Som Tam" — the name alone earns a spot. The creative fruit-based variations (apple, mango, you name it) are genuinely delicious and not just gimmicky. The owner's lizard-covered car outside is both a landmark and a conversation starter. This is som tam with personality. A fun detour from the traditional stalls.
What to order: The tam pa — roughly hewn with cherry clams, hairy eggplant, and other bitter, textural additions. Their watermelon with pla ra and roasted rice is the Instagram dish, but the som tam is the substance. Don't skip the pla som (grilled fermented fish).
"High end: samrub samrub thai, zao ekkamai, soma, charmgang... Must go: soei, som tam jay so"
— r/ThailandTourism · 7 upvotes
tabiji verdict: The furthest from Bang Rak on our list, but worth the trip if you want to taste the future of Isaan food. Chef Eve Palasak's "nu-Isaan" cooking takes traditional som tam and elevates it without losing its soul — the tam pa is arguably Bangkok's most interesting papaya salad. This is the place food writers and chefs eat at on their night off. Not cheap, not street food, but genuinely special. A splurge that delivers.
Frequently Asked Questions
What is the best som tam in Bang Rak, Bangkok?
Based on Reddit consensus, Som Tam Jay So on Soi Phiphat 2 in Silom is the most-recommended spot for som tam in the Bang Rak district. It's a lunch-only street stall famous for its wide variety of papaya salads and fiery Isaan flavors. Hai Som Tam Convent on Convent Road is another top choice for a more sit-down experience.
How much does som tam cost in Bangkok?
Street stall som tam typically costs 30–60 THB ($0.85–$1.70 USD). Sit-down Isaan restaurants charge 60–120 THB, while upscale spots like Somtum Der or Zao range from 100–300 THB. Even the priciest som tam in Bangkok is a bargain by international standards.
What are the different types of som tam?
The main styles are: Som Tam Thai (sweeter, with peanuts and dried shrimp — most foreigner-friendly), Som Tam Lao/Isaan (funky fermented fish sauce pla ra, salted crab — bolder flavor), Som Tam Pu Pla Ra (with raw crab and fermented fish — the hardcore option), and variations using corn, cucumber, or unripe mango instead of papaya. Each vendor makes it to order, so you can customize spice level, sweetness, and ingredients.
Is som tam safe for tourists to eat from street stalls?
Generally yes — som tam is freshly pounded to order, which reduces food safety risks. Go earlier in the day for the freshest ingredients and cleanest equipment. If you have a sensitive stomach, start with Som Tam Thai (no raw crab or fermented fish) and avoid the Pu Pla Ra style. Choose stalls where locals are queuing — high turnover means fresh produce.
How spicy is som tam? Can I control the heat?
Som tam is made to order, so you can always specify how many chilies you want. One chili (prik neung med) is mild, 2–3 is standard Thai spicy, and 5+ enters serious heat territory. Say "mai phet" for no spice or "phet nit noi" for a little spice. Even Thai locals disagree on the ideal number — it's entirely personal preference.
