A friend reminded me that Chuck's used to be a pretty good breakfast spot. It's on Pacific Avenue at Swain Road on the east side of the street (next to Petco). It's a divey-looking diner, but used to be really good. I haven't been there in several years, though...YMMV. Still, it's only a couple of miles north of the UOP campus.
Also, my parents really like Carl's (NOT the burger chain) for breakfast. It's at Waterloo Road and Highway 99. Not real close to UOP, though.
