Hmm so I understood that I’m supposed to cook stuff and follow the recipes on the wall, but every interaction was really lacking in feedback and feeling very confusing.
First customer orders a burger. Right, there’s a box of hamburger patties, but nothing happens when I press E so I suppose the guy next to it wants gold first. The only thing that looks yellow in the room is a box of round yellow blobs, but when I try to give them to the guy they just float in front of his body.
At this point I thought the game was bugged/unfinished and was ready to give up, but after reading the comments here I realized that what I thought was “gold” is actually the “money” stone in the cash register. So now I was able to make the hamburger and the “fries” for the next customer, but then on the third recipe (a soup of raw egg and nuts?) I couldn’t figure out how to get the white stuff out of the mortar, so at this point I finally gave up after all :)
