Luckily, they have a second downtown location at 501 NE First Street, and will migrate there.
The 14th Street location (which opened in 2009), along with Manhattan Café and Market, was purchased by Spanish developer Espacio USA, which has plans to build two mixed-use towers at 1400 Biscayne Blvd. near the Adrienne Arsht Center.
The second location will host a grand opening next month. Customers might just be a bit better off at this place because they have double the space (1600 square feet as opposed to 800), a covered outdoor seating area, and free parking (you can't beat that, especially in downtown). With the double capacity and outdoor seating, the total area equals roughly 3,000 square feet.
Of course, DRB will still have its huge selection of beers. Before the first location closed, you might have noticed that DRB had its own taps. They were brewing their own beer, although it was contract-brewed at Florida Beer Company in Melbourne (soon to be Cape Canaveral). Two of their beers include a "Miami Sun Ale" and a "White Ale." There has even been a suggestion that a possible on-site brewing operation could open up at the new location.
