Can't tell you about the restaurant itself, but their little stand in Mallory square is great! My fiancee and I were enjoying Mallory square at the end of our last evening back in April. A storm was brewing and all the vendors were shutting down for the night. I believe his name was Gary.(one of the owners) and because he was closing up and we were hungry he just gave us the last couple of delicious pretzels he had without charge. We sat and chatted for 15 mins. Really, really nice guy. Wish we had had a chance to go to the actual restaurant, but were leaving the next day.
Just remember... Key West beautiful, but it is HUMID!!!!!!! I almost found myself dreaming of the chilly weather back in the NW.
