About Casa B

Casa B is a modern interpretation of the traditional Spanish tasca, located in Somerville’s Union Square. Our tapas restaurant and cocktail & rum bar, embraces the romance, warmth and spice of Latin America.  It has strong culinary roots in the Spanish Caribbean cuisines of the Island of Puerto Rico and Colombia’s Atlantic Coast, drawing further inspiration from many other Latin American countries and Spain.  We offer a split level atmosphere, where the warm and inviting dining room is in the lower level and the bar is located on the ground level.
