For me, and the list was my personal definition of a "pub" and not a drinking establishment, draught beer and "pub" are inseparable. I think places that sell alcohol but not draught beers are "bars" and that's not to say they shouldn't have a place here as long as it's clear what they are - sometimes it's easy; just look for a surname or a Z in the name . (& of course the name will change every six months too)
Point 4 on my list excludes pure restaurants but not those that allow you to wander in and just buy a drink without restriction, again they should have a place here but clearly defined as what they are.
We have dozens of bars on the site - mostly without reviews - because that sort of place doesn't seem to appeal to the core reviewers; due to our average age I guess. For a good example of this check out the Fleet St / Slater St / Wood St / Bold St area of Liverpool City Centre probably centred on this one.
I think Conrad has said before we shouldn't get too hung up on the Pubs bit of Pubs Galore.
