I went to the Saturday market at PSU a couple weeks back with my wife. I stood in line for about 30 minutes for some Pine State Biscuits and I can tell you that it was worth every second. I had never eaten at Pine State before so I went for the famous "Reggie Delux"...a biscuit with fried chicken, bacon, cheese, gravy, and an egg.
My wife had a breakfast burrito from a place but I can't remember the name...she liked it.
There are lots of bakeries represented at the PSU market and I don't think you can go wrong with any of them for good bread or pastries.
