Some of the finest balls in town were previously something you could hook up with only during daylight hours. Now, SFoodie's happy to say, they come out at night, too. Can you name these balls and the San Francisco restaurant where we snapped this picture? Offer your guess in the comments below.
Congratulations goes out to Sam Gilbert, who correctly identified the ma po tofu from last week's Mystery Spot as being the atomically hot version served at Mission Chinese Food.
