If you want great seafood at a good price head on over to Garcia's or Joe's Seafood located on the Miami River.
Garcia's is located at 398 NW North River Dr in Miami. Joe's Seafood is located right next door at 400 NW North River Dr. You can get to both of them by boat, but dockage is limited so you need to get there early during peak times, especially during the weekends.
Both establishments are small, quaint restaurants with a lot of character.
Located right next to these two establishments is the Casablanca Seafood Market. If you want fresh, and I mean fresh, seafood, this is the place to buy it. They bring it in daily and sell to the public.
Bon Apetit!
