The matcha here is top notch is so delicious, We checked it out on opening day, and the logistics of the place was terrible. The layout to restaurant wasn't planned very well, as the line up really congests the tea room. After visiting it recently the line has improved, and service has become slightly quicker.
I've tried the shaved ice, soft serve, and sundaes in the past, and they are all very rich in matcha. My only complaint would be that the soft serve ice cream melted very fast. On the streetcar, I found myself with a lot of melted ice cream on my dress because I didn't have tissue.
