What should be included on PG

[Strongers]

personally I detest places that pretend to be pubs but are really restaurants, clubs or residents only hotel bars. So on that basis my definition of a "pub" is a business that would

sell draught beer (keg or cask)
not have a charge for entry (except maybe Christmas/NewYears),
not restrict entry on the basis of membership, style, looks, etc,
not require the purchase of food in order to purchase drink,

I think that OB summed it up earlier in the thread.
