It's easy to understand why the Gowanus pop-up Pig Beach found enough summer success to open a winterized brick-and-mortar location: the signature triple-stacked cheeseburger proves that the best things in come in threes. Smoked meat specialities, like baby back ribs and pork shoulder, are also draws, while a chickpea-quinoa veggie burger that's almost as good as its short rib-brisket counterpart will appease vegetarians. Sandwich specials like Italian meatball subs and pastrami on rye keep things exciting.
