Since its founding in 2001, The Upper Crust Pizzeria has fashioned artful thin-crust pizzas in 19 storefronts with modern, architectural touches. Chefs craft specialty pies inspired by local landmarks, from the sundried-tomato cobblestones of the Beacon Hill to the pesto-painted walls of the Green Monster. Diners can opt to spread sweet sauce over a regular or whole-wheat crust or request that any pie be served white without sauce, and combine slices with crisp salads or pounce on the geometric goodness of a spinach square or half moon-shaped calzone. Restaurant interiors are accoutered with modern flourishes such as flat-screen TVs and pan-decorated ceilings, allowing one to lie down and admire their reflection before a postmeal nap.
