I have an issue of Popstar magazine (Stars of Summer) there was a page of questions they asked the JoBros what there fav. starbucks drink was heres there answers

Nick: Iced Coffee. The regular coffee is too strong for me

Joe: I dont like coffee but, depending on if its hot or cold, I like their Strawberries & Creme Frapp., They're peppermint hot chocolate is really good. Also the passion Tea Lemonade.

Kevin: It depends on what time of day........ something like a Mocha Frapp.Chai latte- extra chai no water, skim milk.

hope that helps. :-)
