It was OK. My hickory smoked chicken sandwich was good, but nothing to make me go out of the way to come back. My son liked his burger, but it looked way to big for a kid's portion.
But I'm not a big BBQ connoisseur... I expect they would say their cheeseburger and their chicken sandwich are not what made them, well, Famous.
Oh, I forgot, after Famous Susan brought us a couple glasses of water and took our order, my son had to go. I got up to go with him (after insisting he didn't need me to come along, he came back because he couldn't interpret the signs--"Setters" and "Pointers"--to figure out which one he should go in). When we came back some overeager Famous Busboy had cleared our table.
