Somewhat disappointed would best be the title for my review.
Before I begin, let me say that I have been to other Coffee Tree Roasters. I also am an avid coffee drinker and therefore have a fair amount of knowledge that can be used to compare this place with others.
I visited awhile back. Upon arriving I immediately didn't feel welcome. There were four baristas there and I had to wait over a minute before one of them even greeted me. After ordering I decided upon a mocha. It tasted like hot chocolate. Where was the coffee flavor? All the while I noticed the four baristas standing in a corner laughing with one another while giving off an "exclusive high school club" vibe. Geez!
AND....when I left (mind you there was only one other customer in the lobby) I took up my dishware, as well as some others on a nearby table and the dude working just gave me a look and didn't even say thank you! Things like that really bother me. Let me tell you, as somebody who has worked in retail and food it can be a PAIN to be friendly towards customers, but it's just something that should be done in that business.
Bottom line: Not terrible, but very underwhelmed by the coffee and service. I highly recommend the Caribou Coffee right across the street. The baristas have always been pleasant and the drinks quite good! I have had far better experiences at the Coffee Tree Roasters in Shadyside and Squirrel Hill which tells me that this one certainly can become better!
