Not only they ban CHL but I walked in with my kids and brought some of my own food. The food they serve the is crap and I eat healthy. They would not let me in with it even though I was about to buy foot for my boys and have them play. Screw that.
As for the 30.06 sign, I'm pretty sure it's not the right size. The whole sign is maybe 14"x12". See below.
Inside they have a smaller sign that says that guns are prohibited even on the parking lot.
I was seriously about to leave but I promised my boys that I will take them. I sat on the grass outside and had my lunch then took them in for the last time out of my own free will.
