If there was some way to convert their used vegetable oil into biodiesel, I would bet that the owners never need to buy gas! Them make A LOT of doughnuts, and some people come just to buy boxes of them. But their coffee is pretty decent too, and with two walls of books -- for atmosphere -- they attract a fair amount of people who avail themselves of their free wireless interent, or just come to study or read. It's not a boisterous, noisy place, but sometimes for reasons unapparent to me, the place will be filled with lonely looking men, and no women -- I don't know why! Still, it's a good place to meet people who like to have good conversations.
