Can I open a coffee shop in the office building? Do you need a flue to open a cafe?

Yes, you have to communicate with the property first, and you can open it if you can. As for the flue, you have to go to the flue to cook. I suggest you don't consider the flue, talk to the property first, and then look at the consumption power of people in the office building. Try to cook some simple meals, products that can't be smoked, and is it convenient for water supply and drainage of office buildings? Can you turn on the power? Wait, you need to communicate with the property.
