I saw the earlier thread on late night eating which had some good suggestions for later places, but it left off at 24 hour places. What are your favorite 24 hour places to eat anywhere in the bay area?
My favorite is Sparky's on Church near Market. It's a diner, but it has some of the best milkshakes I've had anywhere. A major plus is that it's salads are appetizing baby greens rather than the slightly browned iceburg "lettuce" you get in most other diners.
