Felix's Seafood restaurant and fish camp in Mobile, AL is phenomenal, it's by the battleship on Mobile Bay. Also Bluegill's in Mobile, great food,live music, airboat rides and gators hang all around the restaurant out back by the dock!
If you like good seafood, Stingray's on Tybee Island has some awesome steamed platters.
Also, The Cattleman Steakhouse in Lakeland, FL is really good. The appetizers are the best, fried alligator, escargot, and deep fried bacon with a gravy sidecar!
