This bar isn't exactly on Sixth Street, but its so great and close to Sixth that it is worth mentioning.
So do you love 80's music? How about 80's music played live by cover bands? If yes, then go to Cedar Street! It is amazing live music that makes you want to dance the night away. The atmosphere is great, the live music is outside and the bars are on the left, right, and on the top balcony. I would say this bar isn't exactly for the typical college undergrad. It has more of a "young professional" vibe.
