Black Dog is a staple of Champaign-Urbana by now. Coming from Texas, I didn't expect to find great BBQ, especially in Urbana, but I'm so glad I was wrong. The food here is fantastic and I recommend waiting out the long line to eat. It's well worth it.
I highly recommend the Texas caviar as an appetizer. If I didn't care about my waistline I would order it every time. The burnt ends are good - there's a reason they sell out like crazy - but I don't think they're the best value for your money. I usually get the hot polish and brisket with the twice baked potato casserole and baked beans. The fries are also great, but I LOVE the potato casserole. You're missing out if you don't get it. My boyfriend loves the rib tips. I think they're the best value for your money, but I get annoyed putting that much effort into eating ;-)
The sweet tea isn't great. I wouldn't order it if you're looking for legit sweet tea. The Carolina red sauce is my favorite. Black Dog switched their default sauce from that to the Lexington something other. Not sure why because I think the new default sauce isn't great at all. The Georgia peach is also good, but of you don't like sweet sauce stick with the Carolina.
I will definitely miss Black Dog after leaving Champaign.
