Food and drink: 5 stars. The coffee is from La Prima Espresso Co. in the Strip District, a local Pittsburgh neighborhood. I really like their stuff. I usually go here for breakfast and can't seem to order anything else but the Huevos Rancheros because it's so good. The portion is easily enough for one person and you possibly could split it.
Space: 4 stars. I really enjoy the atmosphere. The natural light from the large storefront window fills the entire place. You also can sit facing the window and watch passersby on Liberty Ave., one of the main streets in Downtown. The area towards the back where the bathrooms are looks unfinished. There are about four two-person tables and two larger, higher tables for larger groups. I like that he has plants around the place.
Service: 1 star. The owner is an older gentleman with white hair. His mood is very unpredictable. He can have a pleasant conversation, but most times his social encounters are awkward and rude. He openly admits that you might wait a while for your food since he is the only one who cooks, which is nice to tell people. The food can be worth the worth, but he goes about telling people in odd ways. During the most recent visit a group of 4 people sat down and he told them that they would probably have to wait an hour to get food, but said that they would be better off going to McDonald's or something. He never invited them to stay and have drinks, just dismissed them. It's as if he is miserable for having too many patrons to handle and seems to blame people for even going in, yet if you want to take coffee to go he gets upset with you. You also cannot take anything with you because they don't have containers. I would take your own. I can't figure out what he wants from or for his business or the customers, but he could be more accommodating.
