50 (central): Daytime coffee / drink?

Long shot, i know but i am sometimes pottering around the west end on during the day and it would be lovely to have a glass of wine and introduce myself if there's anyone out there in a similar position. I'm happily married (but dead bedroom) 50yo fit, funny gentleman?

I'm a bit stubbly, a bit salt and pepper. full head of brown hair. 5'10 white british. like to dress well and smell good. I'm seeking someone like me.. well adjusted, sane, likes deep conversation, martinis+champagne and good perfume. Discretion a must.
