Ramanathapuram's food scene reflects its location on the Gulf of Mannar. Seafood dominates — fresh fish, prawns, and crab are cheap and plentiful. The town also serves the large volume of Hindu pilgrims passing through on their way to Rameshwaram, so vegetarian South Indian meals are easy to find. The standard idli-dosa breakfast is available at every street corner stall; the rice plates at lunch are generous and inexpensive.
