During the summer back when

During the summer back when I lived in Boston, I'd stop every day on my way to work for a large iced coffee at Dunkin' Donuts. Standard summer fare, iced coffee seemed to be served everywhere beginning the day after Memorial Day. It's the obvious summer companion to iced tea. In winter you order your drink hot, in summer, chilled. So what gives with San Francisco? We have iced tea year-round (understandable I guess since it never really gets very cold) but where's the iced coffee? I can go to Starbuck's and get an iced Americano but I don't want a fancy coffee drink and I don't want to stand in line while people order their grande no-whip decaf iced non-fat mochas with two Sweet'N Lows. I just want an iced coffee. Plain old iced coffee. Anybody know where I can get one? Preferably in/near SOMA?
