If you are looking for strong flavour, go to other places.
The matcha was alright.
Some people say it's bitter, I had authentic matcha in Japan, it's supposed to be bitter. But honestly, the matcha here is just okay. The only reason it's busy is because there are not many other options to choose. When a thing is rare, it becomes precious.
I ordered the one with a cake on top. It was 8 dollars I think. Not cheap, but the whole thing tasted like water except for the cake was a little sweet. Matcha ice cream looked nicely as green matcha but not much flavoured. And they worked very slowly. That was a weekday afternoon. We were the only customer at that time. I was disappointed. I would never go back.
