Two of the best games I've played in recent years (Antichamber and Fez) are now available in the Humble Indie Bundle 11 if you pay more than the average (currently ~$4.60). If you haven't played one or both of these games do yourself a favor and drop a fiver on this bundle.
Johnnie's is the best hot dog shop I've found in the valley. The couple that runs it is very nice and keep the place clean. The hot dogs are delicious (my favorite being a jumbo with chili, cheese and onions), and while slightly above average, the cost is well within reason.
This is a quaint little joint that serves excellent, authentic Mexican food. All food is hand coooked and delicious. The staff is nice and accomodating and the prices are pretty reasonable. From the outside the place may look like a hole-in-the-wall joint but inside is a clean and pleasant atmosphere.
For a quick slice of pizza, Slices is pretty good. They offer a slight student discount and their slices are pretty big. They're not the best pizza in the area, but if you don't have time to sit around they're still pretty good.
