Hub has proved to be a—well, a hub of the new downtown, shaped by the arrival of the urban streetcar and the rebirth of Congress Street as a dining destination. Hub’s food ranges from burgers and meatloaf to elegant variations on comfort classics such as lobster mac and cheese. The most expensive thing on the menu, a take on steak frites, is still less expensive than at other venues downtown—and it’s delicious. Save room for the house-made ice cream.
