In ShortFounded in 1948, In-N-Out locations are known for their eye-catching yellow-arrow logo and spic-and-span red and white interiors. The streamlined menu includes fries, beverages and three types of hamburgers. These all-beef burgers are topped with fresh vegetables and Thousand Island-like dressing on griddled buns with optional American cheese; fries--oversized potatoes with the skins still on--are dunked in cholesterol-free cottonseed oil until just the outsides are done.
