Prequel, a new space designed to house pop-up and events (located where LivingSocial used to operate a similar venture), now has its own bar. UrbanDaddy has all the details about Brick & Mortar, the house bar for the space.
The bar will serve beers (including some local ones) and cocktails (and even sherry), plus snacks like lobster rolls and BLTs. Find it in the basement of Prequel.
