—You've just wrapped a pleasant dinner with a group of friends at Sugarcane or Cecconi's, and the situation calls for a more low-key beer bar. A good-looking one, with arcade games.
—You're in the area on a Saturday afternoon craving a fried catfish slider. Maybe two.
—You've been to Randolph Beer in Williamsburg and Nolita, but heard this one's got six house-brewed beers including a saison, a pale ale, a sour wit and a wet-hopped marzen. You love a good wet-hopped marzen.
—You heard these guys do self-serve beers priced by the ounce, and you're ready to capitalize on the sampling possibilities.
—Your one cousin from Chicago is in town, and that guy is downright obsessed with shuffleboard.
—Um, you just really like beer.
All perfectly satisfactory reasons to find yourself at Randolph Beer Dumbo: the third opening from the folks behind Randolph Beer that comes in the form of a 5,500-square-foot beer hall, opening tonight quite literally under the Manhattan Bridge.
