CITY MARKET promises an “outdoor street party,” with live music kicking off at 9 P.M. At Wild Wing Café, you can catch Jeff Beasley and wind back the clock to the hair metal’s heyday with Silicone Sister. For just five bucks, you get live music, a balloon drop, free party favors, a champagne toast, and a 1 A.M. complimentary goodie buffet.
