[Tagging] Dutch cafes

Plus, you could potentially end up with hundreds of different tags defined, if a lot of people decided to add tags for their favorite dishes.  It seems more reasonable to tag the general cuisine, whether food is available, whether alcohol is available, whether reservations are required (usually only at fancier establishments), and whether the establishment allows children (in the USA, at least, places that mostly deal in alcoholic beverages, rather than food, such as bars or nightclubs, are generally required to be limited to adults only by the terms of their license, but restaurants are generally open to all ages, even if they have alcoholic beverages on the menu).

I don't.  I don't want to revisit each place each week to see whether
the menu has changed.

Well, that's the way it is.  The definitions have to be general enough
so that they can be finetuned to match local circumstances.  It would be
foolish to assume that a café in Hongkong looks exactly the same as in

Also, if you only tag the menu instead of categorizing the place you
only put the burden on the consumer of the data.  Otherwise you get 10
icons on the map for each café (coffee, pastries, egg&chips, ...).  Or,
you have to ask your router to guide you to a place where they have
beefsteak, beer and rum if you feel like that.
