Hi, just some background. I am from New Orleans where we love to eat especially great tasting spicy food. My family always tends to have low food expectations once we leave our area (so many people can't cook who run these restaurants). And of course, Disney runs this gammett (sp?). I will never ever spend any money at Cinderella's Table. We ate dinner here once in late 1990's and never again. The food was cold (I don't like cold steak) the cute Mickey butter was frozen solid (I think the knife bent while we attempted to cut it) and the rolls were as hard as rocks. We could've thrown those rolls across the run and killed some one with them. It was expensive and so very bad.
Rainforest in DTW. Pretty much as everyone above described. Food is mediocre but plentiful, you will wait (even with PS) and service is slow. (However, we ate breakfast once at Rainforest at AK and really enjoyed it althoug overpriced but we were given plenty and made it out in about 50 minutes.
Sci-Fi, after eating here you are going to wish that they would send you out into space as you'll be disgusted when you leave. The only thing they can cook is a burger which is over priced when eating here. We decided to try something else (whole purpose of eating in a seating rest. is so you won't have to eat fastfood). ham sandwich, alfredo noodle dinner and spinach and artichoke dip. They forgot to put the spinach in the dip (quite literally - disgusting to even mention it now), they didn't have any alfredo sauce on the noodles and how in the hell do you mess up a ham sandwich.
As for fast food, Plaza Pavillion MK (have tried pizza twice, no sauce just cheese on top of hard pizza dough) was just disgusting.
I have had many good and great experiences as well.
LeCellier (great)
Garden Grille (great)
House of Blues (good)
Crystal Palace (good)
Tony's (mixed, I had steak which was very good, family had spagetti which was so big 3 people could've split but sauce tasted if out of a can - overall we did enjoy the experience).
Any baked pastry from France's bakery (old time eclairs)
Restaurant at Port Orleans
I know that I am forgetting a few places but oh well. Also, I have never had bad icecream from anywhere in the Kingdoms.
