This ground-level nightclub has anchored the condominium/retail complex at 2016 Main for years, but Mainstage has undergone a major renovation since it was known as Sammy's. The interior cast in a blue light gives 2016 an air of electricity, as house music and DJ nights get people on the dance floor, and most Fridays brings party-rocking cover bands like the Spazmatics. Now open Wednesday through Saturday, Mainstage plans to add Sundays soon. A few small VIP landings offer a semblance of privacy, and the back room (available for reservations) is a cozy little lounge awash in red décor, with its own bar to boot. Parking is still a hassle in the area, but if you don't mind walking a few blocks from your car, you should be aces.
