Food carts and trailers are all the rage now, but when Kierstin Colaceci and Judson Gravel opened Burger Barn in Jeffersonville in 2007, good mobile food was a foreign concept in Vermont.

Their bright-green trailer with a Holstein-printed roof doesn’t travel anymore; it remains tucked in a driveway it shares with Ace Glass & Windows and Cambridge Cutters. But Burger Barn is now a Lamoille County staple, with an exotic menu that has grown to include 35 different burgers — all made with beef from nearby Boyden Farm, unless diners order a veggie patty instead.

Craving juicy beef topped with shaved prosciutto, creamy Camembert, tart Chapin Orchard apples and homemade maple mustard? Burger Barn is the place SEVEN DAYS: Have you ever come up with a burger too quirky to serve?

KIERSTIN COLACECI: No, I’d say all of them work very well together. The Nutty Goat started as a special and now it’s our most popular burger. It has chèvre, maple-crusted walnuts, bacon and a little mayo. It’s delicious. Some of them are really messy, too, with coleslaw or chili. It’s so fun to watch people eat them.
