Came here with friends a few nights ago looking for a small dessert to share and we got a matcha bingsu with mochi - I would highly NOT recommend it.
Maybe we ordered the wrong one but the matcha bingsu was disproportionately flavoured and the entire design of it was poor. They provided condensed milk on the side to pour atop the bingsu but because it was volcano-shaped with no room to actually hold the milk, it just landslided off. The base of the dessert was entirely unflavoured shaved ice -merely topped with matcha powder. Since the matcha wasn't nicely infused into the ice, I ended up just having alternative mouthfuls of either powdery bitter matcha or watery flavorful-less ice. Then there's the sharp contrast of the super sweet red bean to keep the dessert from tasting like nothing. The overall flavours of all the ingredients didn't marry well.
That being said, I noticed the other menu options are actually infused shaved ice so maybe they're better. I don't know. I'm still not inclined to come back considering I didn't find the portion was worth the price.
