Capitol Hill: Not just for politicians, it's a neighborhood

Quick, what's Capitol Hill?

Is it a place where politicians argue? A backdrop for TV news? Or a real Washington, DC, neighborhood, with homes, an old-school diner and even a couple of bookstores?

Truth is, it's all those things. But if you're not from the Washington area, you'd be forgiven for thinking that Capitol Hill is a place where the US Congress meets and not a place where real people live.
