Head to the tapas bars on Paseo de los Tristes in the town centre, and along the beachfront. This is probably the tastiest and most authentic food in town - and it's free provided you're drinking. Restaurants are few and far between, and tend to be fairly expensive. Fresh seafood is the speciality. The cost of living in Adra is unusually low for Spain, and it is relatively cheap to buy fresh produce if you don't mind doing your own cooking.
