Kimmel Center for the Performing Arts
Okay, so PIFA's definition of "late night" is definitely "late night for people who need to go to relieve their babysitters"--the entertainment ends at midnight. But these free weekend evenings at the Kimmel Center do feature a nice selection of DJs and bands, including an apparent battle of sorts on April 30 that pits the raucous West Philadelphia Orchestra against a similar band from Chicago, Mucca Pazza. There’s a cash bar, too, in case you want to get sauced under that crazy fake Eiffel Tower. Or, better yet, see the entertainment, and then head to Bob & Barbara's, or the Tritone, or McGlinchey's...anywhere, really, after midnight. Assuming you don't have to get back for the babysitter.
