While the concept is good and they offer a high level of customization, I did not enjoy what I've tried.
I ordered the mini cone with the cookies n cream dip and vanilla ice cream. It was wayyyyyy too sweet. My mom got the hazelnut dip and it was also too sweet. The chocolate dip layer was way thicker than I expected, which probably contributed to the overwhelming sweetness. The mini cone is pretty big btw and I couldn't finish it; I can't imagine anyone finishing a large by themselves. But If you're a fan of really really sweet desserts, you'll probably enjoy this place.
Also, be prepared to wait a long time, for parking, for ordering, and for picking up your order. And there's probably going to be no room to sit inside if you come during the summer because it'll be packed with people.
