Converyor Belt Sushi Restaurant Theme Help?

[FuchsiaMuffin]

Ok! So I decided to make another human character in my town Wahiawā, and decided to make their house a conveyor belt sushi restaurant, after geeking out over seeing one in someone's house. So far I paid their down payment, I have two conveyor belts and some Japanese items. At first this was a one room restaurant... But then I wanted to add a private room(s), a bathroom, an arcade.... But I need some help/inspiration to pull this off. Any ideas/suggestions? Thanks!

Use Zucker's house for reference?

Thanks! Do you know what the wallpaper is? I have a different wall paper but I like Zucker's more.
