Granddaddy of the roast beef joints is Brennan and Carr. Founded in 1938, when Homecrest was still crisscrossed with country lanes, it's nostalgically decorated like a Civil War stockade, with a parking lot inside chain-link battlements. The somewhat dainty sandwiches are furnished with an undrained wad of roast beef steamed to grayness, served with a decent cup of bouillon for dipping.
