There is a drive thru Starbucks in San Marcos, actually two of them, you'll have to go one exit down from Twin Oaks, it's right off of the San Marcos Blvd. Exit, I get a cup there maybe once a week, Sugar Free Hazlenut Latte, Non-Fat, No Foam..
I've been to that one! But only on test days, I usually bring my coffee to school to save some $... but when I don't... it's a Venti, Non-Fat, Carmel Machiato sometimes w/ a triple shot When it's very needed mmmmm....
