#1 Hang Than (not the bia hoi but the busy seafood stall against a wall - southern corner) Only open at night.
Great cheap street seafood spot. They serve the best mien xao cua in town (glass noodles fried with crab) and ngao xao ot (clams in a chilli lemongrass sauce), about 55,000 vnd per dish. Go the khaoi lang chien (sweet potato chips) too!
Crabs and prawns approx 400,000 vnd per kilo
