Ruby's Diner was founded in Newport Beach in 1982, and now the restaurant chain has locations all over the country. This restaurant features inexpensive, classic American fare, such as cheeseburgers and hot dogs as well as creative modern dishes like the Kickin' Chicken Sandwich and the Vegwich. And just try to resist one of the milkshakes, including enticing flavors such as Butterfinger, Vanilla Black Cherry and Chocolate Turtle. Kids eat free Tuesdays after 4pm.
