Re: Have to wonder
Same rule-of-thumb as pubs - if a busy pub is run by a rude miserable landlord, that is a good sign that the beer is well-kept. If the bar is staffed by an exquisitely pretty barmaid, that is a sign that the beer alone might not be good enough to bring the punters in.
Good beer sells itself. If I want to look at nudey pics, I don't need to look at a beer advert (or even buy ten packets of peanuts: https://en.wikipedia.org/wiki/Big_D_(peanuts)#Promotional_displays )
