Visited twice and lucked out both times not having to line up for long. The first time we came during their soft opening so not many people know they were in business already and the second time during a random afternoon. So I'd say if you don't like lining up, you can still beat the line during non-busy hours. The place is small with limited seating so get your ice cream and go!
In our first visit, a lot of the items on the menu were not available yet or sold out already so it was very limited. We got the Tsujiri Float with matcha soft-serve and the Shiratama Sundae. The ice in the float quickly separated so it was just syrup on the bottom and ice on top. When they had to make the sundae, there was no more matcha soft-serve left so they offered vanilla with unlimited toppings for free. I basically added all the toppings except for red bean and it strangely came out delicious. For both items though, the soft-serve was quite watery. I guess it was a soft opening so they're still in the process of figuring out things, but the place was too busy for just 2 people making the desserts and one on cashier. They also couldn't communicate in English fluently and looked a little confused.
Second visit was must better. Everyone knew what they were doing, and how it was supposed to be done. More staff and better flow. This time we went straight for 2 sundaes. I have to admit, their soft-serve is very flavourful and soft and creamy. We tried the Tsujiri Sundae which we couldn't last time and the Shiratama again along with a matcha cream puff. The consistency for the soft-serve was much better this time and I highly recommend getting the twist. There's something different about their vanilla that makes it so yummy. Lastly, the cream puff was AH-MAY-ZINGG. Potent matcha flavour with a super creamy filling. It was also CASH ONLY during this visit, not sure why.
I would most likely come back again but not during those long lines. They definitely live up to the hype, just not worth waiting hours in line!
