Wow. Ive been in the Grange so many times and I never had any interest in checking out this place. Boy was I so wrong. My coworker grabbed a shaved ice green tea dessert and holy crap, it was good.
He got the medium size which was large enough to share and the flavours were just amazing. I cannot attest to how authentic this was but it was still a tasty dessert. I also haven't tried any of their other desserts and probably won't because I already found a great thing.
The shaved ice had a sweet flavour throughout, had plenty of matcha powder, whipped cream, red bean, green tea ice cream, and sprinkled with a bit of almond slivers for just the smallest bit of crunch.
Having worked in a nearby building for several years, I am so mad at myself for not coming here sooner. I shamelessly ate more than half of my coworkers dessert and I have no regrets.
