Ruby's Diner is located at the end of the Seal Beach Pier -- a nice 10-minute walk. It has the basic decor of bright red vinyl booths with white Formica tables and soda fountains of the 1950s. The menu is just as nostalgic with burgers, hot dogs, fries and drinks on offer. Over the years creative touches were added to many of the Ruby's Diners by developing modified themes to fit the local area. All the waitstaff and managers are dressed in 1950s uniforms. Everyone has smiles and the service is great.
