Ditto the last two posts - "normal" pubs are not the place for kids: family pubs, fine - but a pub is one of the last bastions of adultum (clealy not a word, but you get my drift). The last thing I want to see in a pub are kids.
By the way, I have an eleventh month old so this is by no means the opinion of somebody without kids.
Friday nights is my football night, and after we've played footie we retire to the club bar for a few pints - being a club, kids are welcomed, which is fair enough, but the place is always full of smoke, and I am constantly amazed that people allow their kids into that sort of atmosphere.
