The original Margie’s on Western Avenue may be showing its age—the booths are dusty, the jukeboxes mute—but it brings childhood rushing back on a wave of cherry-topped whipped cream like no other ice-cream parlor in the city. The place opened in 1921. The Beatles, the Rolling Stones, Meryl Streep, Roy Rogers, and Kim Novak have all satisfied their sweet tooth here. Your grandparents may have, too.
