Concierge.com's insider take:
In the enormous, expat-focused Roppongi Hills development, this 390-room hotel with shops, restaurants, an art museum, and a multiscreen cinema has become a Tokyo attraction in itself. Standard rooms have all the mod cons—flat-screen TVs, DVD players, high-speed Internet access, plus unusually large bathrooms (with their own flat-screen consoles). Ask for a room facing west for stunning views of Mt. Fuji. The Nagomi Spa has treatment rooms, a gym, and a beautifully lit indoor stone swimming pool. Among the seven restaurants, the French Kitchen Brasserie & Bar serves a very popular weekend brunch, and the Maduro bar is a chic watering hole. Since the Grand Hyatt (not to be confused with the Park Hyatt) is a favorite for weddings and conferences, it's often completely booked. Reserve well in advance.
