I have been to Black Dog 3 times in the last week if that says anything. I love their food, pretty much all of it. I get their ribs a lot but their burgers and sandwiches are hard to pass up. Don't forget to add on their sweet potato fries and their cornbread (the best cornbread I have ever had). Their other sides are very good but the sweet potato fries are so amazing its hard to pass them up. The chicken wings are possibly the best in town. All of the sauces are excellent, I highly recommend getting the sample sauce tray.
Downside to this place is the wait but if you go early or late you generally only have to wait 15-20 minutes. I also suggest no more people than 4 as it is a very small place. The bar is a great place to sit so don't count it out.
The beer selection is excellent and I highly recommend the flight if you have some time (and a DD). The cocktails are so good and strong, just the way they should be!
My biggest wish is that they will open a second location in Downtown Champaign.
