For my inayofuata trip to Starbucks I want to get something I've never had. Can anyone give me ideas on what I should get?

I've had kuki, vidakuzi N' Creme Frap, caramel, karmeli Frap, Cotton Candy Frap, peach, pichi Green Iced Tea, strawberry and Creme Frap and a Vanilla maharage, maharagwe Creme Frap. Any suggestions?
