I went in December so instead of the regular Tournament of Kings, I saw the "Twas the Knight" show instead. The show was extremely cheesy but it was still enjoyable in a WWE kind of fashion. The food is as exactly as others have described: dry and tasteless. The best advice that I took from others was to save the tomato soup so that I can use it to dip the chicken. The vegetarian meal was pretty bad too.
Be aware that there is a loud cannon going off often throughout the show. The main cannons were located near the gates, closest to Ireland and France. If you're easily startled or have a heart condition, I'd highly recommend asking for a seat in either Austria or Spain. I sat in Ireland and despite our section being the second loudest (to Dragon), our knight was killed off relatively early.
Do I recommend this show? Yes, if your tickets are comped and/or you have kids. If you have to actually pay for the show and/or aren't going with kids, I'd recommend seeing another show because of the lack of content, poor food choices and the high cost.
