I love this place! Since I've moved away from Pittsburgh a few years ago, I really miss it, too. Haven't found something quite like it anywhere else.
First, in my opinion this place has the best restaurant style burgers anywhere. I think they're better than at Tessaro's.
Second, this is the only place I've ever been to that besides just having a fantastic beer selection also knows how to serve each one of them in the correct way. I grew up in Germany and am really disappointed every time I go to a restaurant here and order a good German beer and it comes in the wrong glass or way too cold. You know, like when you order a nice Franziskaner Hefeweizen and it comes served like a Miller Lite in a pint glass with no head and a sheet of ice on top.
At the Sharp Edge, they do it just like it's supposed to be served for every beer you order: right glass, right temperature, right amount of head, and they have all the best beers from all over.
If you like burgers and/or good beer, you can't pass this place up.
