The drink to get here is the Cocamoca. Much better than Starbuck's Frappacino. Mind you, I've never tried the other frozen drinks, because every one tried would be a lost opportunity to get a Cocamoca.
I've been coming here for a couple of years, and the baristas run from pleasant to extremely nice and patient, with only one girl who sighed when I ordered (the Cocamoca is a bunch of extra work), "This is the worst day of my LIFE!" Girlie, it should only be your worst day. I was tempted to order half a dozen more, but they are four bucks fifty, and I'm too cheap for grand gestures.
The location is extremely pleasant, with big windows that open up in nice weather. I haven't found anything as pleasant in my Manhattan neighborhood, I can tell you that.
