Honestly this is the perfect balance on communicating your idea for what the game wants to be and not getting caught up on details of a restaurant sim such as recipes that can take a lot of development time.
I think the gacha idea is really cool and I enjoyed this part of the game and I imagine you could have a thing where you can boost them with duplicates and stuff. But the little animation for it makes it a lot less exciting that what could have been.
I can see you guys ran out of time because of some of the art in the menu and stuff, but overall this could easily be a full commercial game here on itch with a bit more development. Congrats!
