Ok, what I think you are asking is where to eat your meals and get the best dessert with it, right? Not just where to go to use your snack credit for dessert?
I'm actually planning our meals around as many "good dessert" choices as possible, LOL! here's our list, keep in mind, some are NOT the best desserts, but do give a selection besides just chocolate cake. I'll try to list what the dessert is for each.
