Restaurant health codes do exactly that. It seems to me that there are relatively few "black market" or "under the table" restaurants. (Yes, there are food trucks, but it's a recent and relatively smallscale phenomenon.)

Of course, this doesn't make health codes good, necessarily.

But what I'm more interested in - what kinds of prohibitions lead to speakeasies/organized crime, and what don't, particuarly on the scale of the Prohibition, with Al Capone, Elliot Ness, etc. ??
