| +/- amenity=pub
A pub or public house is an establishment that sells alcoholic drinks that can be consumed on the premises. Pubs commonly sell food which also can be eaten on the premises. They are characterised by a traditional appearance and a relaxed atmosphere. You can usually sit down and there is usually no loud music to disturb conversation. A pub would be good location to meet after a day's mapping for OpenStreetMap.
Historically, pubs originate in Britain, Ireland, Australia, Canada and New Zealand, and can be traced back to Roman taverns.
How to Map
Add a node at the centre of the pub and add amenity=pub to it. You should name it with name=*. You may also wish to consider noting its postal code or telephone number if such information is available. If the whole building is used for this feature and its footprint is present in OSM, you can apply the tags on the area if you prefer.
In some countries, local people will often refer to local pubs with the definite article - e.g. a pub called Red Lion Inn may be referred to in colloquial speech as "The Red Lion". This should be included in the name=* if and only if it appears on the signs on the exterior of the pub. For example:  is name=Royal Oak, whereas this is name=The Royal Oak.
Additonal Tags (suggested)
- food=yes - If the pub serves food, or type of food thereof;
- cuisine=<style> - type of food offered (usage as amenity=restaurant)
- beer_garden=yes - The pub has a garden where customers can sit outside. You may wish to add an additional node describing the garden's location if you have decent imagery or GPS data.
- outdoor_seating=yes - The pub has a outside seating, possibly café-style. Useful for urban situations where one can't really describe the seating as garden-like.
- old_name=* - former name of premises.
- operator=* - Operator of the pub, normally the chain or brewery concerned.
- real_ale=yes/<style> - real ale offered or type thereof
- real_cider=yes - real cider/perry offered
- microbrewery=yes - pub has a microbrewery on the premises
- smoking=yes/no - whether smoking is allowed (usage as amenity=restaurant)
- accommodation=yes/<style> - Accommodation offered, or type thereof.
- camra=yes - Listed in the CAMRA Good Beer Guide (UK only). Note that there is a Points-of-Interest file distributed by CAMRA, but the terms seem to prohibit importing this data into OpenStreetMap.
- brewery=<name>[;<name>]* - name(s) of breweries whose beer is sold here.
- amenity=bar - Difficult distinction. In general a bars are modern purpose-built commercial premises, have a more noisy atmosphere, and may be standing room only.
- amenity=nightclub - More emphasis on dancing. More likely to require an entry fee.
- amenity=biergarten - like pubs, but outdoors.
- amenity=cafe - more tea/coffees drinks, less alcohol. Normally not open later at night like a pub.
- amenity=restaurant - Often pubs double as a restaurant, or have an area set aside as a restaurant. Decide the primary purpose of the place.
