Very popular with Thai locals looking for great, home-cooked seafood dishes. Sornthong has been in business for almost 20 years. No frills, just cheap and cheerful.

Located on Rama 4 Road, just past Sukhumvit Soi 24, the restaurant gets very busy between 7-8pm but it is open until 3am. They don't take reservations - just show up and wait.
