Last night I had dinner at Tom Colicchio's Craft in LA for food week. Overall it was good, but... my scallops has more than a few grains of sand in them. When the waiter came around to ask if everything was OK, I didn't say anything. I can't figure out if I didn't want to be a pain, or if I was intimidated. Anyone else had a similar experience at a well regarded restaurant, and what did you do?
