The Champaign counterpart to the Urbana original is very nice and has much more seating, so if you're looking for a shorter wait time this is probably the location to choose.
The burnt ends are amazing and sell out fast--they are freshly available starting at 11 am and 5 pm. Everything is amazing. Their multiple sauces can be a little overwhelming because you might not know which to choose. But they're all good. The sauce flight is a great idea for the indecisive, or for those eating in groups of 2-3.
I love getting a platter with 2 meats (typically burnt ends and beef brisket) and a side of sweet potato fries. The cornbread is a good option if you're looking for something seemingly lighter. I liked the green beans (which are cooked with garlic, tomato, and bacon) but they could use a little more heat.
