The Thursday night seafood buffet was a little off-putting. Are they using corn starch to make the diners feel full sooner? The clams and mussels weren't very warm. They also had a questionable looking sauce as they cooled at the table. The chilled dungeoness crab was great. Unfortunately I didn't make it to the dessert portion. Was that their intent?
