What was the name of the diner where Fonzie and his friends hung out in Happy Days?

Arnold’s is the answer. On Happy Days, Arnold’s was the central diner where Fonzie, Richie Cunningham, Potsie Weber, Ralph Malph, and their friends often gathered in the show’s Milwaukee setting, giving the ABC sitcom a familiar 1950s-style hangout built around booths, jukebox culture, and teenage social life.

Arnold’s as the Main Hangout

Arnold’s served as the best-known social hub on Happy Days. The diner gave the characters a regular place to meet outside the Cunningham home, making it useful for conversations, jokes, dates, and group scenes. Its name remains the clearest answer even though later references in the series sometimes involved changes around the diner’s ownership or naming.

Fonzie, Richie, and the Milwaukee Setting

Fonzie, whose full name was Arthur Fonzarelli, was played by Henry Winkler. Richie Cunningham was played by Ron Howard, with Potsie Weber and Ralph Malph also frequently tied to the same friend group. The series was set mainly in Milwaukee, Wisconsin, and Arnold’s helped ground the characters in a recognizable neighborhood setting.

The Diner’s Role in Happy Days

Arnold’s reinforced the show’s 1950s and early-1960s atmosphere through its diner-and-jukebox style. It was not just a place to eat, but a recurring classic TV location where the show could bring together school friends, family concerns, romance, and Fonzie’s larger-than-life presence. That steady role made Arnold’s one of the most memorable locations connected to Happy Days.
