"The first Mexican seafood restaurant in Detroit. Look for special menu items on Mondays and Thursdays. Happy hour takes place on Tuesdays and Wednesdays from 6 to 9 p.m." Marisco's has created a word of mouth reputation for anyone seeking high-quality seafood, Mexican food or Mexican seafood. All of this good food is available plus a mural of Selena as a sultry mermaid. Take time to check out the elaborate outside mural too, with its crosslike anchor surrounded by brillant fish.
