For my suivant 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 biscuits, cookies N' Creme Frap, caramel Frap, Cotton Candy Frap, pêche, peach Green Iced Tea, fraise and Creme Frap and a Vanilla haricot, fève Creme Frap. Any suggestions?
