The cheerful, high-energy brick-and-mortar iteration of Baxter Key and Andy Gerry’s food cart opened in December 2017 to instant acclaim. Highroller’s signature lobster roll and the lobster cheese crisp taco can be customized with a variety of sauces and add-ons. There’s also an excellent burger and local brews on tap, including selections from partner Peter Bissell of Bissell Brothers Brewing.
