They always said home cooking was best so how about npc who sales food to guests this should also include wax food. Maybe make the chef upgraded by guild or group quests. The upgrades could be ability to store x food type or number or how many people it can actually serve. And make the rewards better food though sometimes make it worst but make rngess depends like on evaluations. Also maybe have options to find new animations or outfits for chef. This could also be sold in crown store ( animations)

Let funds mostly go to guild but also pay chef.
