Surprisingly hip, especially since it's part of a strip mall, you usually find places this trendy in tucked away, older neighborhoods of Pittsburgh, It's a little pricy for burgers and shakes, but you're compensated by the atmosphere. I have a feeling that people either love it and are regulars or tend to visit once and find it a little overrated.
I had no complaints with my burger, except that they forgot to put something that I ordered on my burger (you can custom-order a burger by filling out a paper scorecard in the center of your table) and I was too timid to mention it to my waiter. I would return here, it's also conveniently located by the cinema, with a little walkway that cuts through the strip mall, so if carefully scheduled, dinner here and then a movie would be a good night out.
