Jack Lyons was a long-time hamburger stand and café founded by its namesake. It operated for most of its existence on Broadway Avenue between 5th and 6th Streets – where the Parkade now sits. Lyons already operated a couple other restaurants before starting his famous hamburger stand in 1916.
Earl Swartz continued the business when Lyons no longer could. Lyons died in 1947 and Swartz in 1963. The restaurant was still operating as of 1965, but had closed by 1967 when J.C. Penney opened a baby store there. For some time after, until at least the 1980s, local butchers and restaurants advertised what they referred to as Jack Lyons-style hamburgers.
