Used to go to the Watford one as well, with mates after work. That was a few years ago when it was not so busy. Always took our own clubs and usually played the snooker game. Can't remember top score though.
Too busy now in the evenings so don't bother, but love the concept and think it's great for getting non-golfers into the game.
Think the Watford one may be the original one and was started by two brothers who thought driving ranges were boring?
Think some of those who need complete silence should go there and hit shots while they announce the latest offers on Jaegerbombs!!!
