The Cafeteria

The Cafeteria On Warner Bros. Studio Tour

The Cafeteria refers to Caltech's cafeteria where Sheldon, Leonard, Raj and Howard often go for lunch  and sometimes breakfast, along with others. The cafeteria is seen in many episodes. Sometimes, significant events occur in the cafeteria, such as the introduction of Dennis Kim and the addition of Leslie Winkle to the Physics Bowl team of Leonard, Raj and Howard.
