I have never had a bad meal at WDW. Some of my meals have been better than others, but none of them have been bad. Yet I have posted on this board that there are restaurants I will probably not revisit. An example is 'Ohana. Our food and service there were well above the line of "acceptable" - we just didn't enjoy it as much as other WDW restaurants, so it's on our list of "been there, done that, no need to go back." Tony's is on the same list. We've been to Tony's twice, and the meals were not bad, but they weren't among our favorites either.
Name any restaurant at WDW, and I can guarantee you that it will be on at least a few DISers' lists of favorites. Sci Fi and Donald's are two of our very favorite WDW restaurants, but they are among the restaurants that get the worst reviews here on the DIS. On the other hand, no restaurant escapes criticism here. LeCellier and Boma are among the most popular restaurants with DISers, but I've read plenty of negative posts about both.
When you read restaurant reviews on the DIS, you need to keep them in context. DISers are not your typical WDW visitors. We are generally super-planners who care very deeply about every aspect of our WDW experience. Otherwise, why would we take the time to post on an Internet site? Because we put so much time and effort into planning our WDW visits, we tend to examine every aspect of our visit under a microscope. Under those conditions, an event that would barely be noticed at a restaurant anywhere else turns into a major ordeal. For instance, last year DH and I visited San Francisco, a city known for great food. While we did have some great meals there, we also had a couple of meals that were worse than anything we've ever had at WDW. Yet this is the first time I've mentioned those bad meals anywhere on the Internet.
This is why I think DISers should base their dining decisions on what sounds appealing to them, not on a few reviews they read on this board. The reviews are helpful if they are used to get an overall feel for what a restaurant is like. But if we had decided not to visit Sci Fi or Donald's based on the bad reviews we read, we would've missed out on some of the most magical moments we've had at WDW.
