I know this should theoretically be possible, since Arsil's custom registers and icarus_allsorts' http://modthesims.info/download.php?t=524698 both have similar functions, but for different objects. Still, I haven't been able to find a mod that lets me customize the bills of fare in my cafes and bars whenever I place these objects on community lots, instead of going with the EA defaults.

It's a pity; I'm REALLY into customizing my food/drink places in my towns and I'd like to touch on these places as well.
