I believe this cheesecake store is actually a chain originating from Taiwan. Some of my friends visiting from Tokyo had a laugh because they had no idea why they had affixed "Japanese" to it and no idea why there was such a long line. I know that the recipe is derived from the Japanese "cotton cheesecake", but it's not quite the same. I wish they would make everything from scratch rather than what I suspect are mixes. My mom's is much better than these cakes and the ones in Chinatown are pretty much the same( but cheaper and quicker), they certainly don't compare to what you see in a bakery in Tokyo. There is a three ingredient recipe on YouTube that replicates as well. The service is nothing like you would see in Japan either which is unfortunate because I think they use the whole Japanese thing as a selling point. Its not bad per se, but it's not great, I would eat it, but I would never again wait for it.
FYI: Yelpers, not sure if anyone cares but, "jap" is a derogatory short form for Japanese.
