Ethnic Desserts in MSP area

I am teaching a seminar on The Psychology of Eating and I have received a little money from the U to bring the students a different ethnic food each week. We decided in class to make these all desserts. So, I am in need of help. Can anyone recommend places to get good ethnic desserts here in the twin cities area? Please suggest specific desserts if possible. I have already done Mexican and Greek. So skip those, but anything else?

Thanks very much!
