Everything from the customer service to the unique flavors is excellent at Anteny's.
My SO and I stopped in on our first night in Pittsburgh, and as it was our first time, the man behind the counter explained the whole menu and (very patiently) got us probably 10 different samples. EVerything we tried was really great, but some of it would have been hard to eat a whole scoop of. We ended up getting banana with oreo which my boyfriend LOVED and the fresh mint frozen yogurt (definitely lighter than the ice creams) which I really enjoyed.
Everything is very reasonably priced, and they give out punch cards as well. Worth a visit if you're around!
