DH and I went there in 2003. We got a coupon from the website, I think it was $7 or $8 off. It was fun (our knight won!). The food was ok, you eat with your hands, but they do give you a warm cloth when you are through eating. We got some bread, a rib (I literally mean 1 rib bone with meat on it), some beef, a half of a baked potato, and I don't remember anything else. Dessert may have been a cookie.
It was over all a good experience, but we probably will never go again. I think it was about $70-$80 or so, I realize that you are also paying for the show and experience, but a little pricey in our opinion. I am glad that I went once for the experience though. They do have lots of cool things to look at while you are waiting, armor, swords, etc ...
