A pizza joint from Rachael Marie, who earned the title "Pizza Regina" (or pizza queen) during her four years at Roberta's, features a selection of approachable, New York and square pizzas – whole & by-the-slice – that rely on only fresh, seasonal and high-quality ingredients. The Roost is home to the first DC location of Slice Joint, with another location in New York City. Slice Joint's menu features by-the-slice options – cheese, white, pepperoni, square pepperoni – as well as round and square whole pies. Guests can also customize from twelve+ toppings.
