Kodtalay Seafood Buffet Sukhumvit
3070 Sukhumvit 70 Alley, Bang Na Nuea, Bang Na, Bangkok 10260
Start with the 499 THB tier on your first visit to calibrate how fast your table actually grills, then move up to 799 THB once you have the rhythm. Come at 4PM on a weekday for fully stocked live tanks and bearable outdoor air. The crowd that fills this place every evening has figured something out: the value-per-bite ratio here is strong for this end of Sukhumvit.
You walk in, point at a live crab in the tank, and ten minutes later it is on the grill in front of you. That is the short version of how Kodtalay Sukhumvit works.
Sitting on Sukhumvit Soi 70 in Bang Na, far enough east that the central Bangkok crowds have not found it in force, this open-air grill-buffet operates across a sprawling outdoor layout with individual table barbecues. Each group manages its own cooking: seafood arrives raw, the grill is hot, and what you do next is up to you. Live aquariums run alongside the dining area so the rock crabs, soft-shell crabs, and king prawns are genuinely swimming until you point at them. The kitchen handles the rest of the spread: a sushi and sashimi station where chefs work to order, spicy crab curry, mussels, mango sticky rice, and a dessert counter with fresh fruit and ice cream.
Two buffet tiers cover different appetites. At 499 THB per person you get full access to the grill proteins, cooked seafood stations, sushi, and desserts with no time limit. The 799 THB tier adds sashimi. Neither tier locks you out after 90 minutes, which matters when you are waiting for a crab to cook through.
The sister branch at the Riverfront draws the tourist traffic. This Bang Na location draws the locals: Thai families who live south of On Nut and know the soi well, plus the Bang Na residential crowd who treat it as a neighbourhood institution. Weekend afternoons from 3PM fill fast, and by 6PM the outdoor section runs loud with the sound of grills going and conversation pitched over them.
The nearest BTS stop is Udom Suk, followed by a taxi or motorbike to Soi 70. Driving is easier here than in central Bangkok, but parking on the soi is limited. Come before 6PM on a weekend if you want a seat without waiting.
