It is an Icon for both the Hilton chain and Chicago. The Grand Ballroom is amazing. Considering there were about 2,000 of us, the meals and buffets were really tasty. At the sit down meals everybody had each course within 5 minutes of the first plate hitting the table. The servers were attentive and met each need promptly. Even though it was cold and snowing, it was nice to be able to see some good Chicago Blues at Buddy Guys Legends across the street.
