Flatiron Hall has become a welcome addition to the techy venture capitalists of Flatiron District. The two floor establishment’s lower level beer hall has a 1920s speakeasy style. The food is delicious, especially the pastrami Ruben spring rolls (because the pastrami comes from the legendary Carnegie Deli). If pastrami is not your thing,you can munch on smoked rib-eye sandwiches and homemade spicy potato chips. As for the beer, the hall features beer specifically from Greenpoint breweries that only serve Flatiron Hall and its big brother, Houston Hall.
