I've been to several different locations of Dave's Famous BBQ, this was the worst.
It's usually very good. This time the service was very slow and the food was terrible. My brisket was tough, dried out, oily and tasteless. The others' brisket was tough and dry. The chicken tenders and muffins were about the only edible items among the five of us. Very sad.
But, please don't let this stop you from trying other locations. Most are very good.
There are so many alternatives in this area, I just won't try this again.
