This is the place to go for high quality goods. It is Mitsukoshi's main headquarters. They have a great selection of clothing, Kitchenware, and so forth. The basement floors are like a food museum. They sell a wide selection of food such as sushi, salads, bentos, etc. Also, you can find Harrod's tea products and sweets.
My friend took me here for my birthday. The service is impeccable and the view is SPECTACULAR. The nicest view in Tokyo in my opinion. This tea room is more traditional than other tea rooms that we frequent in Tokyo. The seating can be somewhat uncomfortable for someone with long legs such as myself. However, the food is delicious. We ordered a traditional tiered serving platter. The waiter also asked us if we had any food preferences which was nice as well.
