Great drink. I'm glad to find out that I can actually go and get one sometime. I thought they had totally gone the way of the dodo.

Never liked them. They always seemed pretty low class to me in general, like Arby's. Then again, I'm more of a water and coffee person myself.

I think they have one in the DQ counter in the Longwood galleria near the BI.

I've seen it in many convenience stores, small grocers, and cafes.

I first discovered it at Au Bon Pain, but they don't sell it anymore.
