I came here on their opening day and they were really busy. The orders came out relatively quick and the amount of mango in my mango drink was surprisingly a lot. I'm comparing to the portions that NYC dessert places usually give and it generally isn't as modest as this place.
I came back on the 2nd day of their opening and everything was running fairly smoothly. Orders also came out relatively quick while dining in. As we were sitting there a long line formed for takeout orders and the staff here handled it well.
All the drinks and desserts were tasty, the staff were efficient. Next time I'm in the area, I'll return for a drink or two.
