Here's what I'd do at Movie World.
1. Covert the deli into a crepe cafe (goes much better with adjacent ice-cream shop, and they're quick and very cheap to make). Because they're so cheap to make, a very substantial profit can be made without guests feeling ripped off. Also I'd extend the cafe seating area by enclosing the outdoor area behind the shop, and make it into a nice comfortable dining room.
2. Greatly improve the quality of Gotham burger bar, probably best achieved by getting an established external party to run it. I'd also make it part of their contract to have the Wild West burger bar open whenever the park is expected to be busy enough to make it worthwhile (agree on a fixed minimum level / number of guests).
3. Refurbish and reopen the building near the front of the park that used to be "Stars bar" as a new restaurant (could still be licensed) selling high quality, but fast service asian meals. Again this would be best run by an outside business, but I'm sure if the food was good and the prices were right it would be extremely popular.
4. Review the menu at Ricks and evaluate whether it should be changed or not.
I'd give all pass-holders a 10% discount on all food and beverages. That would serve to encourage pass-holders to eat in the park rather than outside it.
I'd look carefully at each of the dine-in restaurants (not only at Movie World but all the parks), with the aid of the appropriate specialists, to see if there's opportunities to theme them, adding some fun elements. The best example I've seen of this is the projection mapping technique similar to the one shown in the video, but that's probably best suited to a more formal restaurant, perhaps like the ones at Sea World Resort. Elsewhere, more simple but still effective themeing / entertainment could potentially be added.
Lastly I'd launch a very well publicised money-back guarantee on food quality at all food outlets in Village parks. It would be simply "enjoy your meal or your money back"! That should give guests the confidence to try eating in-park, as well as put pressure on the operators of the outlets to ensure they do provide a high quality meal to every customer. Yes there would be a few guests who would abuse such a guarantee of course, but if the quality is in fact good, the benefits of such schemes far outweigh the costs.
