When we want good bbq, we drive to Lexington, NC. But we don't always have 3 hours to devote to a meal, so when we want bbq that's passable, we go to 521 BBQ. I recommend a chopped bbq sandwich with white slaw on a bun with their sweet bbq sauce along with some fries or baked beans. Don't try to go all out and get something amazing here, just stick to the basics and you'll leave satisfied.
And be warned: the vinegar based bbq sauce has Franks Red Hot in it - it's WAY hotter than you're expecting it to be.
