Caffé Demetré can get pretty crowded at times, and sometimes you can be forced to sit near the entrance like we were. This isn't a huge problem unless it's cold outside. All the cold air prompted me to order a hot drink.
Service was friendly, even if I wasn't particularly polite when I ordered without looking at the server. (I had an iPhone in my hand, and I didn't know how to pause the game so I blindly motioned toward some general area of the menu as I ordered.)
Some chocolatey coffee drink.
Total damage: $5-ish.
