Three day visit.
Reception/check-in: exceptionally well-done. At the same time the concierge went over details about two items we had booked through the hotel before arriving. She then discussed plans for our upcoming visit to Kyoto, we agreed on the appropriate tickets for trains, and the next day tickets and comprehensive travel information were provided in a folder. Concierge staff are excellent.
Our Park View King room was outstanding. A corner room with a view that was incredible. I was up one morning photographing the sunrise, minute-by-minute.
Restaurants: Here comes the worst!
New York Grill: reservations booked through the hotel in advance were missing, inaccurate or whatever. Few minutes to straighten that out. Seven minutes to communicate that I wanted a CC and Soda for my drink. All courses were rushed... then we waited and waited for the check. Table was very plain. Food OK, nothing more. Very overrated restaurant, and New York Grill is their "best" one!
Girandole: We wanted to order one Tasting Menu dinner and one Ala Carte dinner. Not allowed, even though we often do this in other restaurants. We got the feeling that they really were not interested in serving us, so we left. Indifferent staff.
Girandole: Breakfast Buffet. Very impressed by the food, layout and service. Great server. Flawless!
Delicatessen: A bit expensive but very good. However, don't expect free coffee refills.
Kozue Japanese: Excellent food, prepared about as artistically as you will ever see, on hand made pottery pieces. Love this restaurant for the atmosphere, food, service and variety of choices. We had dinner there two times.
Summary: if this is in the area of Tokyo where you need to be, the Park Hyatt has gorgeous rooms and excellent views. The concierge staff can help you with anything, and get it right the first time. I would not choose the New York Grill for dinner. (Actually, if we were in Tokyo one more day, we would have eaten in one of the restaurants located in an underground arcade below the office building the hotel sits on. Not hotel- affiliated, and more of a local, less expensive opportunity to try Japanese food.)
In our trip to Tokyo and Kyoto, the Park Hyatt was the best hotel. The New York Grill was the worst restaurant. But Kozue Japanese was the best restaurant.
