We haven't gone for the past 3 years. We didn't think the food measured up to some of the other meals you can get nearby (Crystal Palace, Chef Mickey's, even Tony's). The mac & cheese is frozen Stouffer's, we don't like it at home either, though & the stuffing tastes like its from a box or frozen also. The meats didn't seem to be seasoned much. BUT, the salad is very good and if you prefer a simpler, blander menu (we feel it compares to a Morrison's or Piccadilly type cafeteria) it may be fine. We have met several people who like it for the reason that it is blander and not as highly seasoned as many places.
Oh, on a side note, one place that is overlooked, but has a great price and simple fare is the buffet at the Trail's End at the campground. It's a quick walk over to Contemporary and a boat ride across the lake. The prices are the cheapest of any buffet at Disney and the same families that told us they love the LTT also enjoyed this one.
