Gotta love Tazza D'Oro.
This place is by far the best coffee within a ten minute walk of Carnegie Mellon... though that isn't saying much. The wait staff is very friendly and the coffee is A-OK!
Occasionally the coffee has an oiliness to it, which typically means the beans aren't fresh, but overall I'm satisfied. The hot sandwiches and soup are the most edible thing on campus and the pastries are amazing. If the prices were a TINY bit lower I would give the place 4 stars.
