Last year, and previous years too I guess, a big lobster tail dinner usually ran around $45-50 BZ. Good chicken or fish entrees $15-25 BZ. Quality is easy to find, even with the street vendors. Good food is just about everywhere. Small places with dirt or linoleum floors generally are cheaper and the quality is still there. If you want more upscale ambiance, you will pay a bit more for it. Some of the restaurant web sites will post their menus and price lists, check a few, they should give you a ballpark figure.
