Editorâs note ⢠In this regular series, The Salt Lake Tribune explores the once-favorite places of Utahns, from restaurants to recreation to retail. â For a vast swath of western Salt Lake County a half century ago, the only nearby place to see movies in an indoor cinema was at the vast-itself Plaza Theatre in Kearns. It was built in 1964 with 950 seats, a wide screen and a full stage â to also allow live performances â and advertised itself as Utahâs third largest.
