UC Virgins more questions

I have searched these answers but some go back a few years so sorry in advance.
I understand that you eat when you want, how does this work, do you have to arrange a time when you board?
Can you visit the bar anytime, we just want to have a drink up at the bar to say we have done it , as this UC return flights may just be a one off, is it best to wait till its empty then sneak up there?
Finally on our return night flight, if we don't want to wear a sleep suite will we be the odd ones out?? We just want to lay down, chill and enjoy not necessary actually sleep, as I said before, I doubt we will ever be able to do UC again but wanted to do it once.
Sorry if questions asked before
