"We have to"... Why? If there are things that are undoubtedly cafe-bars in the world, with its main use depending whether you're a pensioner or a hipster (Bristol has at least 10 such on Gloucester Road alone), why on earth can they not be mapped? Even if Mapnik doesn't like semicolons, it might still accept the string "cafe;bar" (and "bar;cafe"), or "cafe-bar". In France there are tens of thousands of cafe-bar-tabacs - currently they're mapped with a random value from that lot, which is crazy. What I hate most of all is the loss of information that occurs at the "have to decide at some point" stage. The note field could save some of this usefully, even if unstructured in form.
