Could not find the specific town where my Cracker Barrel is located (Crossville, Tennessee). But, since I live not far from CB's original location, thought I would put in my 2 cents' worth.
I love CB's food and would probably go there more often, except that I live in Tennessee's largest retirement community where many older folk are a little hard of hearing. I often hear it said, "Let's go to Cracker Barrel. Oh, wait. It's so noisy there, I can't hear any of the conversation. Instead, let's go to...."
I doubt this is a huge consideration for CB. At least they have done away with their "smoking section". Good going CB. I still love your food!
