My husband and I are going to be seeing "Wicked" at the Gershwin Theater (51st and Broadway) on a weeknight. We're looking for a place to grab dinner that isn't overly formal or fine-dining, but that offers something interesting and good. We'll be a little pressed for time, because we're coming off a tour that ends at 6pm and the show is at 8, so something relatively quick would be nice. We just don't want to get stuck in some tourist trap. Any suggestions?
