A tycoon section similar to FNaF 6, I would see people coming and interacting with the things in the pizzeria

5 save files

5 save files to be able to have many different pizzerias!

pizzeria and design

change the color of things, an original name and your own decoration and structure!

all at your fingertips...

weird animatronics...

for a cash bonus, you could become a night guard and survive in your pizzeria with the animatronics walking around and stalking you, it would be 2d and you would have to use the environment to your advantage

Extra money and bills...

if the customers have a good experience they could give you some nice extra money, at the same time if you check inside the attractions and the arcades etc, you can get bonus money...

the bills would be based on the lights of the place, the electricity etc.

These are some of my ideas, if you want to see more we can talk in private, I'll be happy to give you many more!
