well its going to be tough because of the sheer number of people who travel to State College for games but you do have options. I recommend Faccia Luna on South Atherton street for great pizza and pasta. They have a nice atmosphere with a big wood burning pizza oven in the room and a nice beer selection. Altoona is different though. It is pretty much chain only resto's there.
Other State College options:
Champs-sports bar, decent food, good beer selection, great atmosphere
Alto/Zola/Gamble Mill- same owners, fancy, great food, reservations will be necessary
Corner Room- right in the center of town is a tradition for a lot of people. If anyone tells you to go to the Diner, don't, it's terrible now.
Cozy Thai is really great Thai Food in downtown.
Home Delivery Pizza- great pizza/stromboli's in a nice bar type place.
all of these are lunch and dinner options. Breakfast, there is only one place to go: The Waffle Shop. Prepare to wait in line with the other hundred thousand people that will be in town. They have three locations in State College: North Atherton, East College Ave, West College Ave.

If you're looking for fine dining in Altoona, the Altoona Hotel is fabulous! They've been under new mgmt for sometime now. Great wine selection. I believe they offer over 25 wines by the glass. Same owner as the Knickbocker around the corner. The Knickerbocker is a more casual bar/restaurant with great wings, hummus, salads, and a good Sunday brunch. I love their outdoor seating.
