Pat's Drive In

"For a living, we eat everything; but one of our favorite hobbies is eating chili dogs. There are few places we like practicing this hobby more than the vintage Tucson drive-in known as Pat’s. Although the dogs themselves are not inherently breathtaking, Pat’s tops them with a chili stew of beef, beans, and fresh chili peppers. (Chili is also available by the bowl.) On a chili dog, the chili is spread across a line of mustard and is customarily garnished with a sprinkle of raw onions.Depending on the seasonal variety of peppers (or possibly depending on how sadistic the cook is feeling that day), Pat’s chili can be ferociously hot … or it might be merely peppery. 

Although chili dogs are Pat’s main claim to fame, serious students of the burger will want to sample a Big Pat, which is a double hamburger garnished with not only cheese and chili, but also mustard, pickles and lettuce. The Big Pat comes on a bun, but longtime devotees pay extra to have it on toasted bread. 

With an order of Pat’s excellent salty French fries and about a quart of cold soda on the side, here you have a great all American meal with a uniquely Southwestern flavor."
