Blue crabs from the Chao Phraya region are the most commonly grilled here. The char adds a slight smokiness that complements the sweet meat. Cracking the shell at the table is part of the experience — staff will split it for you if you ask. Best ordered alongside the river prawns so both arrive together.
Tips from diners
Order with the pepper garlic sauce, not just plain — it coats the meat once you crack it open and makes a real difference.
The prawns come whole and are split lengthwise before going over the coals, which chars the shell and concentrates the natural sweetness. Multiple reviewers flag this as the single best thing on the menu — the size and freshness make the difference. Prices vary by market weight, so ask before ordering if budget matters.
Tips from diners
River prawns are priced by weight — confirm the price before they go to the grill. A medium pair typically runs 400-500 THB.
Ask for the spicy tamarind dipping sauce on the side — the default sauce is milder and the spicy version matches the charcoal flavour better.
A standard but reliably good version of the Thai staple — the wok heat here is higher than most shophouses manage, which gets the slight char on the stems that makes the dish. A useful balance against the richness of the seafood.
Tips from diners
Order one vegetable dish per table — it breaks up the seafood and adds something green to a very protein-heavy meal.
A fast-moving wok dish where the clams open in the chilli-fragrant oil. The roasted chilli paste gives depth beyond a straightforward stir-fry. Multiple visitors recommend ordering this as a second dish while waiting for the grilled items to cook. The broth at the bottom of the plate is worth soaking up with rice.
Tips from diners
Order this while you wait for the grills — it arrives in minutes and keeps the table busy while the prawns cook.
The soup comes with shrimp, squid, and fish in a broth that's sharper and more herbal than many tourist-facing versions — galangal, kaffir lime, and bird's eye chilli are all present. It serves two to three people as a shared dish alongside the grilled items.
Tips from diners
This is the right size for two to three people sharing. One bowl between the table is enough — it's rich and the grilled mains are filling.
Lek & Rut has occupied the corner of Yaowarat Road and Phadung Dao (Soi Texas) for decades, competing directly with T&K Seafood across the street in what locals call the green-versus-red-shirt rivalry. The restaurant sets up plastic tables on the sidewalk each evening as Chinatown traffic inches past, and the charcoal grills stay lit well past midnight. Most seafood is bought fresh from the market earlier in the day and goes through high turnover, particularly on weekends when tables fill by 7pm.
On Friday and Saturday, tables fill completely by 7:30pm and people wait on the street. Arrive at 6pm or after 10pm to avoid the peak.
There is an air-conditioned indoor section if you prefer to avoid street-side fumes. The outdoor tables are the classic experience but the indoor option exists for hot nights.
Exit Wat Mangkon MRT and walk south on Yaowarat Road about 10 minutes. The restaurant is at the corner where Phadung Dao intersects — look for the red-shirt staff across from the green-shirt T&K Seafood.
Keep cash handy — this is a street-side operation and card machines are not reliable here. ATMs are on Yaowarat Road within walking distance.
