I really loved this spot...a great resturaunt to stop and relax. I have heard it is either gone or combined/changed. Since I have not been back in a couple of years, I'm not entirely sure.
It's still there. They closed Big Thunder Ranch BBQ and put a few BBQ items on Casa's menu. Minor exterior changes, like a fountain, but the overall feel is still the same. Except that food isn't as good anymore, but just like the East Coast, they've standardized most of the food items on property.
