Marvin's (often called "Marv's") is the home of the famous GCB's (Garlic Cheeseburgers). They also specialize in pizza and burritos. All of these are featured throughout the week by their "daily specials." They also deliver at nearly any time of the night. Marv's delivery service is very helpful to students "pulling all-nighters" and generally, for anyone who gets hungry late at night.
You'll find the famed restaurant at 202 South College Avenue, just a short walk from campus.
