The Happy Burger is a 1957 institution now feeding a third generation of hungry people. A late-60s neon sign and canted windows add to the retro look and feel.

Inside, meat is grilled fresh, fries are cut in-store, and the peanut butter milkshake is made with a scoop of Jif. While you wait for your order to be custom-grilled there's lots of Pepsi memorabilia to look at.

McDonald's started much this way on Rt 66 in San Bernardino CA.
