I've never actually been to the physical location, however I've had their catered food on numerous occasions. I'm not generally a huge fan of barbecue style food as it tends to be a bit heavy and meaty for my taste, but I make an exception for YinzBurgh!
This place is crave worthy.
Excellent pulled pork, macaroni and cheese, beans, coleslaw, and hot sauces. I definitely look forward to occasions when I get a chance to eat this, and one of these days will actually check out the restaurant itself.
On the other hand, avoid the salads. They're pretty sad and seem like they were just poured out of a pre-mixed salad bag. The meat on top is still good, but doesn't make up for what's underneath.
