Last week, I had a really cool conversation with Pierre, owner and head chef at La Forchette. He came to this country and ended up cooking for Katherine Graham, owner of the Post. One of the folks he cooked for while at Ms. Graham’s was Warren Buffet. Apparently he eats, “Lamp chops, hamburgers, and peanuts.” He cooked for her for a while and then in 1978 he bought the restaurant for $20,000. Back then Adam’s Morgan hadn’t really rebuilt since the riots of 1968. He ended up cooking for President Clinton at Graham’s Martha’s Vineyard condo.
