I had a chance to go last week on the first official day they were open and didn't have to wait hours but almost all the flavours were sold out.
Ended up ordering taro and got it in about 30 mins. I really liked it with the coconut shavings and I'm not a big fan of coconut in general. The small mochi balls were great and topped with whip cream to top it all off!
So why 3 stars? The way they make each order individually is too slow. They have to look pour the ice cream on the flat freezer, wait for it to freeze, painstakingly scrape and roll the frozen ice cream, then add the toppings, etc. And that's one order. It just takes too long. They have 3 going but the lineup is out the door. Who wants to wait an hour for ice cream?
