A traditional Japanese sweets shop & tea house from Kyoto, Zenkashoin is located on the 5th floor of Shibuya Hikarie. Since Hikarie is still very much a new mall/building, the stores and shops are pretty crowded but my friend and I got lucky enough to get a seat here for tea time. We ordered the 1150yen tea set that comes with a drink of your choice (coffee, tea, green tea, matcha, etc) and a choice of dessert. The dessert is a small delicate size and it wasn’t too sweet. We liked the matcha castella icecream sandwich more than the matcha circular castella.
If you sit by the window, you will have a nice overview of Shibuya and the rest of the cafe still has a nice zen-like ambiance. They also sell their ceramic plates, tea sets, and more so you could take a look if you’re interested.
