Burgatory has become one of those places where I take my friends when they come to Pittsburgh from out of town. Wow. That list is selective and Burgatory made it. Organically. They deserve it.
My recommendation: Make your own burger. They have a completely customizable burger option where you can choose everything from the meat to the bun (or the lack thereof!) to the cheese to the rub to the toppings you want on it! Also, if you have room in the inn, try a milkshake. They're all good. I mean, you have to get a milkshake, right?
The quality of these burgers is great. It's like BRGR except better and cheaper (I said it). Every once in a while they have gotten my medium, medium-well . . . But no harm. Burgatory is set on making that burger right.
Decor inside is awesome. This restaurant was actually ahead of that design curve when they first opened in this location (what a glorious day). I respect them for that. They have this cool garage area where the windows open to the outside. There are also many Tvs lining the walls to watch any game you care to see. It's great for a night out with your lady (or fellow), your friends, or kids. Versatility like that is hard to come by.
Do your tastebuds a favor and eat a dang good burger from the place made famous preparing what it claims to make best . . . Burgatory.
