If you like Middle Eastern food, Jerusalem (right near campus) is the best! Bonus: screened patio seating, which is lovely in nice weather. http://www.jerusalemrestaurant.com
If you head North on University Avenue from campus, you’ll get to Katherine’s, which is great for brunch or lunch, and Bonnie Brae Ice Cream across the street. Perhaps not middle-of-campus vibe, but if you’re looking for nearby variety, I can recommend both of those.
