Best place to start is to check out the club q and a, it will get you a feel for the club rules and etiquette. Then pick a night and go along, tell the staff when you first arrive that you haven’t been before and they will show you round the club and answer any questions that you have. Don’t attend the club with any expectations, you may not get anything on the night and always remember to ask before trying to get involved in any scenes that are going on.
