This is by far the best ice cream chain. Like people have said before, its kinda pricey, but I just buy the smallest size and my fiance and I share it, plenty of ice cream for two people!
The flavors are amazing and the choices are many.
Best thing to get is a waffle bowl (VERY tasty) and split it among two people. For larger groups we bought one kind of ice cream and bought it by the gallon (pre-packaged) at the store itself.
