It is a great time. First, the odds that you will be seated, have ordered and will have food in front of you by 8:00 are slim. It is not uncommon for a 7:25 to be seated at 7:45. So if you do not have a window seat that faces the MK, (and the odds are against it),then you will have to get up from your table to view the show. Not a big deal if you haven't been served yet. To increase the odds that you will not have food served, don't arrive too early and don't be in a rush to order. Arrive 5 minutes before your ADR and you are almost assured of running out the clock such that you won't have to interrupt your meal for the fireworks. The servers are pretty good about holding your food in the event that you want to leave your table.
