I've really only been to one in Marietta Georgia and because of that experience have never been back. But I'm happy to hear of your good experience.
I too find the food at CB pretty good, especially by interstate restaurant standards. There is usually a wait and the parking lots are nearly full all of the time so most people must agree. All of the other restaurants and fast food joints I have tried off of I-95 are terrible. They are usually very dirty with nasty food and rude or inattentive workers.
Oh, the food is great, which is why we would go. However, the waits were always way too long for a road trip.
