We came across the shop on a walk around the area and decided to try it out give the TripAdvisor recommendation. We had a piece of the original version which was refreshing and not too sweet. Recommended.
I imagine the owner of this place started out baking in her home and when guests complimented her on the cakes she got the idea of opening this take-out shop. Towards the end of the day they run out of some choices. This is certainly the best cheesecake in the area and arguably in Tokyo.
