Where was the setting for the TV sitcom "Alice"?

The TV sitcom Alice was set in Phoenix, Arizona.

The series follows Alice Hyatt, a widowed mother who moves to the Phoenix area with her son Tommy and works as a waitress at Mel’s Diner. Most episodes center on the diner’s staff, customers, and the everyday pressures of working-class life.

Alice aired on CBS from 1976 to 1985 and was based on Martin Scorsese’s 1974 film Alice Doesn’t Live Here Anymore. Linda Lavin played the title character, while Vic Tayback portrayed the diner’s irascible owner, Mel Sharples. The sitcom ran for nine seasons and produced 202 episodes.

The setting is sometimes remembered simply as Mel’s Diner, but the diner is the workplace rather than the city itself. Phoenix is the broader location that makes the question’s answer specific. The show also inspired the short-lived spinoff Flo, centered on waitress Florence Jean “Flo” Castleberry.
