I've been once. We wanted to love it. We did not.
There was no line at all but our order took over 15 minutes (we got cookie dough cones). I really can't figure out what took so long.
These are not cheap treats which would be fine except they aren't tasty either. Literally only good for a photo op as they are presented beautifully. No one could finish theirs as they made us nauseated and had the consistency of play dough. Some tasted fine. Others were gross. None were great.
Staff was pleasant enough... I MAY come and try something else but will definitely not go out of my way for it.
