As far as the difference between the main dining room and the restaruant (portofino's) is about 1500 people. The main dining room serves 1500 people at one time and Portofino's serves maybe 30. If you ever want to see how difficult this must be...trying standing in a kitchen that serves 1500 people. I am amazed that they can accomplish this. If you are unhappy with that particular meal...send it back and get something else. You can get a bad meal in a 5 star restaruant.
