America's Best Seafood Dives: Half Shell Raw Bar, Key West, Florida. Don't try to count all of the license plates that cover the walls of this sprawling former shrimp warehouse on the dock. Just tuck back into some briny and broad-shelled Gulf Coast oysters; mammoth, buttery-sweet peel-and-eat shrimp; and devilishly addictive fish dip, made from house-smoked local catch.
