I only had the Tsujiri sundae to be fair. I can't say I liked it very much. Might go back to try something from their warm menu only because I love matcha green tea!
Wins: soft serve ice cream, matcha flavour, mochi balls
Things that could use improvement: rice added crunch, but it gave the sundae a weird burnt taste; too much red bean paste that made the sundae too sweet for me; cost was a steep for ice cream
