I would consider it a sit down - it's a little buffet. I had never been, but one of my fellow countrywomen at Guest Relations encouraged me a few months ago. It's decorated in the Wild West That Never Was theme which appeals to so many Germans (and kids of all countries!)
I was impressed that they rustled up a huge amount of veggie food for me - they even brought out a huge fruit plate which I couldn't eat, and my server insisted on packing it up for me to take away to my resort.
