I had no idea there were long lines/waits to get this cheesecake.... I just happened upon it on my way out of town in the station and walked right up... nobody around and no limits.. buy them all if you want... I should've bought two! (It was around 4pm on a Sunday)
You have to know what to expect with a Japanese cheesecake or you might be disappointed. I think the lower reviews here are rating on simply whether or not they like the cheesecake. I am giving it five stars because as Japanese cheesecakes, or Japanese cakes/bakeries go in general, this is as good as it gets! I was excited to stumble upon it because we lived in Yokohama years ago and this was my favorite treat. I prefer less sweet, lighter desserts overall. If you're a NYC cheesecake fan or a double sugar in your coffee kind of person, you might not like this very much.
Here's my tip: eat some right away, while it's warm, if possible but as fresh as possible for certain. Then refrigerate and try again the next day. It's like two different cakes. Some prefer day of, some prefer day after... I like both equally.
