This place is the sort of place where I can imagine acting totally uncool in if I ever got invited over for drinks.
It is slick, brooding, a little unpredictable and stylish. Sounds like the characteristics of a really hot man. That's it, that's the answer to why I think I would probably act really uncool - I'd most likely be a bit tongue tied.
However, I could probably pull myself together for long enough if there was a chance of an invitation to have a bath in that amazing room!
