Does London Bridge have waiting rooms, preferably heated?
http://www.nationalrail.co.uk say there are waiting rooms 'available'
and 'located on the platforms 1 and 2'. It also says it has a
'Women-Only Waiting Room' on 'Platforms 1 and 2; Platforms 3 and 4.'

Now I'm looking the station map on the site and seeing pictures of seats
on the platforms but no waiting rooms...
