Chanthaburi is famous for its noodles, which are called sen chan; you can taste them at any of the food stalls down by the river, along with Vietnamese spring rolls and muu liang, a spicy pork broth. For a wide-ranging menu of Thai and Chinese dishes, such as spicy salads and thick curries, head for Chanthorn Pochana (102/5-8 Benchama-Ratchutit Rd.; tel. 03931-2339). They also serve wines made from local fruits, such as mangosteen, at very cheap prices.
If you're in the mood for Indian vegetarian food, make for the tiny Sony Yadaw (Si Chan Road; no phone), where you might also spot a few gem traders at work.
