I agree with the PP who said that eventually you'll have to rule out every restaurant at WDW because somebody will have had a bad experience.
Overall, in all of our trips, I've never encountered a restaurant that I think was so terrible (or even so bad) that I could not see its appeal to anybody. There is one restaurant (WCC) that my family did not care for at all, and to which we will not return in the foreseeable future, but it is packed every night with happy looking diners and is beloved by many, so that's a sign that it's obviously appealing to many. There are other restaurants that don't appeal, either because of their cuisine or theme, but those are personal decisions and don't reflect on the quality of the restaurant.
Ultimately, I suggest checking the menus online and making educated decisions. Read reviews here and elsewhere, but if someplace appeals, then give it a try. Isolated service and food issues happen everywhere, so don't take singular reviews as signs to avoid a place entirely if it appeals to you and your family!
