You want alligator? Of course you do. You just might happen to know a great allgiator etouffe recipe. Oh wait. That's me with the recipe.
Well either way, Wholey's is a Pittsburgh institution. And anything you want as far as seafood goes, you will most likely find it here. They have a great meat section and produce available as well.
If visiting, this just screams Pittsburgh. You can't really get a more old world vibe than this.
