Before this review, I want to note that I am a big meat eater, but I am not from a location known for its barbeque. This may not be the review for you if you are from any of those areas.
I have been to Black Dog around ten times in the last year. I definitely prefer this bigger Champaign location over the one in Urbana. I normally order the combo platter. The brisket, burnt ends, and hot polish sausage have always been good. The ribs can be inconsistent - sometimes done well, other times with very little meat. The pulled pork is solid, but I have definitely had better. There are plenty of options for sides depending on your tastes. None of them are bad, but the Mac 'n Cheese is my favorite, especially with some of the Hot Georgia Peach BBQ sauce added on top.
One thing that could ruin your experience here is that they often run out of items. I went with friends once at around 7 or 8 p.m. and they did not have more than half of their meat options. 5 or 5:30 p.m. is the ideal time to go. That's around when they start serving burnt ends again after the lunch rush.
