I can't believe no one's reviewed this place yet. The Big Bang is (literally) an underground dueling piano bar. They're located underneath The Library. This is probably the only bar on Mill Ave. worth spit because it's got a gimmick other than scantilly-clad college girls dancing on tables (here they dance on -pianos-!)
But seriously, The Big Bang is a blast. They've got a rotating group of musicians that take turns on piano, drums, bass, and electric guitar to bang out requests and awesome renditions of practically anything you could ask for...Journey, Billy Idol, Snoop Dogg, Beastie Boys, Weezer...
If you're sitting up front expect to be singled out, pulled on stage, forced to dance, or have raunchy love songs composed just for you, especially if it's your birthday or your bachelorette party. Audience participation is what makes it so much fun. I imagine thespians would dig this place.
Gets 4 stars cause the joint can get INSANELY packed on Saturday nights with drunken college kids...not that it's bad for them, but bad for me and you! While it's a little classier than the clubs and bars above it, songs can get hilariously vulgar, so be prepared!
