There is a Trader Joe's nearby in La Jolla Village Square, and a Whole Foods across the street next to the Sav-On. Open from 7 a.m. - 7 p.m. weekdays. Because of proximity, much of the med school eats here. Round Table, incidentally, is the only place on campus that sells beer. Also often has music, poetry, communists, etc.
Food is pretty good, and the atmosphere is interesting.
Very limited hours, and good food specials. Especially good when you need a caffeine fix. Other food places on campus include Muir Rathskellar, LaCasa, Munch Box, Revelle Deli, Revelle and Muir Dining Commons, Ice Cream Hustler, and the VA Cafeteria . San Diego has many wonderful places to eat. The following list outlines many favorites of medical students, but it is by no means all inclusive.
