Casual local seafood chain popular for shrimp, oysters and catfish, plus a few land options.. In Short Started by the same folks who created Half Shells and Rockfish, this local chain delivers a similar menu. Brick walls, maritime art on the walls and booths and seats all add to the laid-back ambiance. The seafood-dominated menu does have non-seafood options. Oysters in the half shell are among the popular for appetizers. Cajun-influenced entrees include the crab leg platter. Salads, sandwiches and po'boys are also available.
