Along Parsons Boulevard one cold night in January, a crowd of people in heavy winter coats line up for the buses that will take them to Rosedale, Hollis, and Pomonok. But behind a small storefront just steps away, Luna de Xelajú offers a transporting experience of a different kind, to somewhere much warmer. The restaurant’s front room resembles the classic New York City pizzeria counter, with pies sitting in a glass display case to be heated by the slice. They do a brisk business, and their slices are popular with a diverse crowd, but the pizzas are an afterthought for most of the place’s clientele, who come to Luna de Xelajú’s front counter for the Central American-style pan.
