I was in last Thurs (14th) from about 12 until 3pm and there were around 25/30 guys in which was excellent but from conversations with guys in there its random as to when its busy really.
You really never can tell its just pure luck. I was there last month on a Monday morning and it was sensational. Was there a fortnight ago same day same time and I would say it was absolutely desperate. Been going well over a decade and can’t ever recall it being so bad.
