The 1960s and 1970s saw the rise of several steakhouse chains across the country. Perhaps one of the most successful was the Bonanza chain, started in Westport, Conn., in 1963. Billings had several Bonanza locations over the years. The original location at 923 Grand Ave. has been home to Bonanza Health Foods since 1976, but retains the characteristic shape of early Bonanza restaurants. The Heights location, at 1341 Main St., is now occupied by Bugz's. A third location, at 446 S. 24th St. W., was later home to the Riverboat Casino before the building was demolished to make way for an AutoZone automotive parts store.
