@design_RG I dont know who but i know what I'd do.I'd find a quiet place alone for us to chat, have a private dinner maybe or something, and hang out.
Anywhere public would get too much attentiona nd distract from enjoying the person. Moreover, I would expect any one famous would be used to people showing them off like a trophy and few people would want to just get to know them as an ordinary person. So I see it as a sort of date that would be more rewarding for both of us, at least if its my only and first date with the person.
That said I dont find many famous people appealing largely because I am not attracted to the sort of personality that would thrive when exposed to fame. So I really dont know who I'd pick.
