Three words: Sponge cake cheesecake. It's good however I would never line up for it. There's other places that also offer Japanese cheesecake (before Uncle Tetsu came to Toronto) so one can try branching out to try other options too.
Uncle Tetsu prides themselves for providing a strict QA process and selling only "perfect" ones. Mine came without a logo branded on it and less fluffy than other ones I see on Yelp - what happened Uncle Tetsu?!
