I must applaud them for three things: having potato pancakes, being open 24/7, and having the independence of thought to offer a shake made out of pie (which I've yet to try, but feel I must.)
The only restaurant in San Bruno with a view. From this hilltop diner, you can see across the verdant valley to the hills of SSF.All their pies can be made into shakes.Also, dat Bavarian burger.
