I came here with my friends, I really enjoyed their shaved ice here. We went on an evening that was relatively very cold; so at first I was hesitant, however, their ice was so well made and blended in with the sweets that I barely felt I was eating ice at all. Usually for shaved ice at other places I'd taste the ice shard textures which I'm not a big fan of but for Cups it didn't really feel like I was just eating ice at all. We ordered tiramisu/black sesame/etc.
I'd say if you're full on food, a cup size is definitely enough. But if you've got a decent stomach for desserts, get the bowl! The tiramisu one comes with the actual slice of tiramisu cake, so goood.
