Yes people wear towels in all areas…there’s a small courtyard for smokers and dressing gowns are provided if needed.
People chill in the bar/cafe area and the lounge generally most of the action happens on the top floor.
Nearly everybody there is very respectful and a gentle “no thanks” is all that’s needed to avoid any unwanted approaches. Friday afternoon shouldn’t be too busy aso probably a good time for a first visit if on your own.
The staff are very friendly and should be able to give you quick tour of the facilities
Making or avoiding eye contact are the main ways of indicating your level of interest in someone…and most guys prefer to go to a private room for fun
Hope you have a good time
