I'm sure you are right, I used to use the Troc fairly regularly at
lunchtime in the early 60s, - and a couple of times at night
accompanied by a male friend from work, so perhaps we didn't
stand out too much! Another pub which I haven't heard mentioned
was the Falstaff which I seem to remember had three floors, one
with a similar clientele, one with 'working girls' (or so I was told),
and one for the rest of us! It was close to Old Square, and not far
from the Kings Hall Market, but I can't remember which street it was in.
Kind regards
Dave
