Irish Kevin's is the best!!!! I lived in the keys five years ago for the summer. It used to be called Hammerheads. Irish Kevin is a guitar player/ singer, who involves the crowd a great deal. He plays Irish drinking songs, gives away free drinks, it is a total blast. He used to play all the bars down there, but he ended up getting his own bar. Also in Key West you can drink in the street, so grab a drink in a bar and, bar hop!
