The special, hot and skinny.
Except that's my coffee shack, not Starbucks. It's way cheaper - $2.50 for the 16-ounce special latte, and I have a punch card, buy 9, #10 is free. Please don't ask how many punch cards I go through in a month.
Right now the special is White Razz - white chocolate and raspberry - and it's amazingly good.
