How do I tag a sports bar?

Oddly enough we don't seem to have a well-defined way of doing this. Normally there are 2 approaches:

• use an adjectival key (I.e., one which does not standalone) with the same name as the main tag (i.e, bar=). This is not recommended* as this key is already in use to indicate that other types of amenities (restaurants, hotels etc) have a bar on the premises.
• use a similar key postpended with ":type", i.e., bar:type=*. This currently has a minimal usage with a single object tagged. I think this is the better option.

The low usage of this type of tag makes it quite hard to recommend one or the other. This is certainly something worth discussion on the tagging list: off the top of my head I can think of wine bars, whisky bars, gin bars, enotecas and cafe-bars which might all benefit from some kind of subtagging.
