From what I remember...
The ice cream they use is from Nestle (but considering they make everything else in house, you may let them pass on that._
Dutch Dreams makes their own whip cream. They have different toppings, like dark chocolate sauce, nuts, sprinkles. They have fresh fruit for toppings and they make their own waffles for some of their other dishes.
Visually you get some great looking deserts at the end of the day. Big portions for some of their deserts that fills-like a meal. It just takes a while to make.
Just looks at the pictures you see from the desert and you'll understand.
The decor is subject to personal taste (so i won't go there but some people like it)
