Where would I go to find a proper English gentleman?

I know the archetypal English gentleman isn't that common of a thing to actually see in the UK, especially if you're coming as a tourist.

However, if I wanted to encounter a proper English (or British really) gentleman, where would you suggest I go to encounter one? Any restaurants, bars, etc that you'd suggest?

I know this is a bit of a silly question but it would be really cool to actually meet one.
