A great independent coffee shop. Ambiance is phenomenal and there is a good mix of crowds throughout the day. I've seen everywhere from a business troupe, to a hipster crowd to groups of medical students studying for boards. Business is fairly steady throughout the day, however I've never had a problem finding a table except during breakfast rush on the weekends.
Service is excellent. Everyone who works here goes way out of there way to extend great customer service and are extremely friendly outgoing individuals.
Espresso is very good. A sweet bold flavor without too much acidity, which lends well with most drinks. Baristas are very experienced with making quality beverages and of note, make excellent milk foam. Probably one of the best places I've had a cappuccino in Pittsburgh although they tend to pour a little wet unless you specify otherwise. They also have a wide selection of coffee and will French press most for you upon request.
There is also an abundance of plugs which I've found vey rare in the coffee shop world so this also makes it a good place to work on your laptop for a few hours. They do have free wifi, which you have to get a tag from a barista after about 2 hours to continue using it. A small hassle but ultimately the wireless has is pretty fast.
Ultimately this is probably my favorite coffee shop in the city and I'd recommend it to anyone.
