The cake is good, and actually very good. It's $8.88 good, and for good value for the price and size. There is a distinct cream cheesey texture to it which changes depending on whether you have it fresh (hot) or cold. (Note: There are good Japanese cheesecake recipes online if you want to give it a try...we found very similar/reproducible texture and tastes, if you're into baking that is.)
However, it is definitely not 1+ hour wait good, especially not in the heat, rain, and eventually snow. (Luckily, we stopped by during the soft opening and never had to wait...can you imagine no line?). I would argue that it's better to NOT have the cake until the hype is over (if it ever ends) or they find a way to increase their yield, as you'll likely be met disappointment from high expectations and realization of wasted time. So until the quality of the food (which is amazing) can justify the stress it places on the customers (which is horrible), 2/5.
