Kodtalay Riverfront Seafood Buffet runs an unlimited seafood spread on the Chao Phraya at a flat 693 THB net per person with no time cap. The floor is enormous by Bangkok buffet standards, with open-air decks running right up to the water and a wall of live tanks holding crab, prawns, and shellfish that guests point to and send straight to the grill. There is no course structure. You eat at your own pace for as long as you want.
The operation sits on Soi Charoen Krung 58 on the riverside edge of the Charoenkrung/Chinatown corridor, and it has built a reputation for volume done well rather than fine dining technique. Kodtalay Riverfront Seafood Buffet pulls in crowds nightly, and the Google listing sits at 4.9 stars across more than 48,000 reviews, which for a buffet of this scale is unusual.
You arrive, pay the flat 693 THB, and the rest of the visit is self-directed. Staff walk you past the live tanks first so you can pick your crabs and prawns by hand; tagged trays go to the charcoal grill or the steamer depending on what you ask for. Stations ring the dining hall: a sashimi bar with staff slicing to order, a cheese-bake counter for scallops and mussels, a grill line, shellfish on ice, Thai hot dishes, and a long sauce bar with the green nam jim seafood that shows up in most reviews. Seating is communal and loud, fans overhead, the river moving past. Weeknights fill up after 6 PM and weekends need a reservation through the Facebook page or the phone number. Turnover is relaxed because there is no time limit, so expect to wait during peak hours even with a booking.
The grilled river prawns are the headline item, oversized freshwater prawns pulled from the tank and laid over charcoal until the shells blister. Live crab goes the same route, picked by the guest and cooked to order, usually steamed or stir-fried with curry powder depending on what you ask the kitchen for. Cheese-baked scallops are the buffet's crowd dish, split shells bubbling under a layer of melted cheese straight from the oven line. At the sashimi bar, a rotating selection is sliced in front of you rather than sitting pre-cut under plastic, which is why the station draws constant queues. Tying it all together is the house green seafood dipping sauce, a sharp lime-chilli-garlic nam jim that regulars cite as the reason they come back.
