Calvin Trillin's daughter lives in SF. He was here visiting (and promoting his new book "Tepper Isn't Going Out"). According to Leah Garchik @ SF Chronicle he ate burritos at La Cumbre Sunday night and dim sum in Richmond District Sunday morning. After his dinner at La Cumbre he said "My father had a theory that you couldn't gain any more weight than the food weighed. So if you ate a pound of really rich chocolate, you wouldn't gain more than a pound. I gained a lot of weight last night because those things are really heavy."
