Pat O’Brien’s feels like a 1950s American frat party that never ended. The quintessential New Orleans party address offers souvenir cups full of rum drinks, bawdy songs at the piano bar, and a courtyard with fountains spouting flames. The always-crowded Pat O’Brien’s is guaranteed to deliver a good time. You can chill out on the patio or try to stump the piano player with a song from your alma mater.
