London for lunch?

I actually took this picture last summer in London. This quaint little pub/restaurant is just down the street from Westminster Abbey.

Last night I had the best dream.

I dreamed I went to London for lunch. Yep. Just for lunch. I walked around Covent Garden, ate at a little outdoor cafe, and picked up a chicken pasty for my sister to eat for later.

Then I went home.

Wouldn't it be wonderful if we could just take a short lunchtime trip to London?
