Fast-food chain attracts a drive-thru crowd with its made-to-order burgers and specialty sandwiches.

In Short
Since 1951, this quick-serve restaurant has catered to on-the-go motorists, pioneering drive-thru dining and a broad selection of distinctive fast-food items. The menu emphasizes burgers like the best-selling Jumbo Jack--a thick patty topped with lettuce, tomato, ketchup and mayo-onion sauce--but value items like stuffed jalapenos, bacon-cheddar potato wedges, and ''monster'' tacos are popular, too. Breakfast and sourdough sandwiches, salads and real ice cream shakes round out the offerings.
