The Naugles fast food restaurant chain was founded by Dick Naugle in 1970 and lasted until 1988, with a few stores remaining until late 1995. It featured an American and a Mexican kitchen. Popular items included the cheese burrito, the bun taco, the combo cup w/ chips, the Naugleburger, the Ortega burger and more (Bethany wants me to make sure everyone also knows that Naugles had burritos, and shakes, and taco salads as well). A new business group formed in the last few years has been working on bringing the chain back; see articles at The Orange County Register, OC Weekly and Wikipedia. This effort is not affiliated with Del Taco or with any prior owner of the brand.
