Inside a 1970s Airstream trailer at the William Vale hotel, Andrew Carmellini (of Locanda Verde, the Dutch, and Lafayette fame) and team keep the vibe loose and delicious by churning out a simple menu of the ultimate comfort food. The burgers, wrapped in a wax paper sleeve, come with a mix of cheese and a special tangy-sweet sauce on a potato bun. (All the burgers are available as singles or doubles.) There’s also a veggie burger, made of black beans and mushrooms, and waffle fries. Don’t leave without a soft serve—especially the Berry Gibbs, with strawberry, Nilla wafer, and sweet cream, which lives up to all the hype. And yes, there’s a lot of hype.
