And this is coming from a former Vegan. Jones' BBQ is perhaps the best place to eat BBQ in the city. At least, it's the most established, and the most well-known for authenticity and consistency. I myself love the beef brisket, the baked beans, and the cake, but I wouldn't turn down anything there.
The only think to complain about is the high prices (worth it, though), the richness and sweetness of the meat (but it slows you down so you don't eat too too fast), and that sometimes it's slow at lunchtime. But who's in a hurry? I need a whole afternoon to enjoy all that FOOD!
