The Boulevard Diner is a historic diner at 155 Shrewsbury Street in Worcester, Massachusetts. It was built by Worcester Lunch Car Company in 1936 as #730. It is a well preserved instance of a barrel-roof diner that the company made in significant numbers in the years before the Second World War. It is eight bays wide and four deep, with entrances at the sides, sheltered by the ends of the barrel roof. The eastern entrance is enclosed in a 1950s steel-and-glass enclosure, and the western entrance is accessed by an enclosed stair; both still have their original wooden doors. The diner is covered in yellow ceramic panels with red lettering reading "Boulevard Diner". It is attached to a single story brick flat-roof structure which houses the kitchen.
