I saw that corner bakery too. It's a 5 block walked through the middle of the hospital campus. Probably at least 20 minutes each way. If you are really on foot, I would probably check out the facilities inside the VA hospital. I would probably go west - down the hill - either to 13th east with lots of University eateries (the Pie (pizza) and Market Street Grill (sea food, pricey) are excellent plus a couple of hole-in-the-wall hamburger places - or down to 4th south which is full of most of the fast food chains and restaurants easily available.
