I am a heavy traveler and I can honestly say that without a doubt, the Hyatt Union Square is the best boutique chain hotel in the United States - rivaling most independent boutique hotels. Great location, unique design for the public areas and the rooms, high service levels, exceptionally clean, and an excellent independent restaurant (The Fourth) integrated into it so you don't have to leave for a meal - and, room service comes from the same kitchen! The burger is memorable! This is the most "un-chain-like" hotel within a major hotel brand. The Hyatt Union Square is now my default hotel when in mid-town/lower New York.
