The Derby is still a good spot to eat, but I liked it better prior to the Fantasmic "era". Used to be a lot more of a pleasant place to eat dinner--even had a piano player entertaining, and a bar that was actually open!! Nowadays, it's become sort of a pre-fantasmic feeding hole, with a large # of guests not there really for a good meal, but because they need to eat at this restaurant so they can take advantage of the FDP.
Always sad to see folks screaming for their checks BEFORE they even place an order--everyone looking at their watch so they won't be late for Fantasmic!!
These days, when we eat at the Derby, we always do so at a time when the Fantasmic frenzy has abated. A much more pleasant time to eat !!
