None. Illuminations isn't really a "fireworks show". It is a multi-faceted show of lights, sound, water features, projection screens and an occasional fireworks rocket. You really have to be seated or standing around the lake to appreciate it and there are no restaurants that afford you a great view. The best you can do is try to get an outdoor table at Rose & Crown. That is by far the best option and even that is not great, especially since there are so few tables with views. Best to eat and then find a spot around the lake.
