Simply awesome. Incredible BBQ. Fantastic specials. Great drink selection. CANNOT GO WRONG. The biggest downside is the wait (often 30+ minutes). \
When you get there you write your name down on butcher paper and it is your job to know where you are on the list. You can't call ahead to make a reservation and they won't seat your till everyone in your party is there.
Also, their Wednesday Cuban special is nothing short of incredible. This is BY FAR the BEST Cuban I have ever had.
But if you can get a seat you will not be disappointed. DONT leave champaign/urbana without having tried Black Dog
