Thank you for the first hack

about custom food: We all download custom food to allow a sim cook it as a new choice in the fridge...
and we can change the restaurant menu if it is owned by a controlabe sim to add them.
but if a sim goes to a nightlife restaurant for example, all he is gonna find is the origional sims restaurant food....
so,I want the custom food to appear in these restaurants...i don't know if its possible
