This is a very expensive ice cream place so be prepared to pay an arm and a leg. The line up is not very long but about a 15 minute wait. A regular ice cream cone alone is close to $7 after tax. The menu is not very clear, if you want a mixed cone or a matcha, is the same higher price.
The sundae is very thick and heavy with matcha flavour. I have the shironama sundae ($9) which had 4 mochis and red bean. The ice cream melts fairly quickly so eating it fast is the key.
The sundae is small, and the shaved ice is the same price. I would recommend getting the shaved ice since there is more to try.
If you're craving matcha, I would recommend going to uncle tetsu instead which has more value for money and just around the corner.
