If it's a chain then IMO, your wife is right, the vast majority of corporate BBQ restaurants are crap. There are exceptions but I have not found many. If it's a one-off joint then I'm surprised. In my experience owner- opearator-cook run joints are usually pretty good and they usually have a great understanding of their product, cookers & technique. Sorry you and the family had the bad experience.
