My favorite coffee place (link) has offered to add this to his menu for me, but the barrista is not sure exactly what it should taste like. I told him just refrigerate some sweetened espresso and serve in a frozen glass. He is a perfectionist however and might like to try it at a place that does it well. Can anyone tell me about places in DC (preferably downtown) that make a good (great) caffe fredo??? Also, sources for the correct glassware?
