Since 1996, the Grey Dog brand has meandered the lower strata of Manhattan, with a homey feel and a menu of sensational sandwiches (apparently in the "Michigan style," which, you know, who knew there was such a thing?) and a breakfast service that can subdue almost any hangover that leaves you ambulatory enough to leave the house. Every location of Grey Dog is generally forever busy, so be prepared for a short but doable wait, especially during the breakfast and lunch rushes.
