DJs: Walking through Pat O'Brien's front door is like stepping onto Bourbon Street, and the Orlando location of this bar is modeled after the New Orleans original, complete with patio, flaming fountain and dueling piano bar. In fact, Pat O'Brien's claims to have invented the concept of "warring pianos," so be sure to take in the show. While you are enjoying the music, sip on Pat O's other claim to fame: the Hurricane. Other popular drinks are the Purple People Eater and the Skylab. Be sure to bring a designated driver because these mammoth cocktails pack a punch! Casual dress.
