My partner and I have a 9 hour layover on our way to LHR on Sat. 1/15. We arrive at 12:44PM and depart on AA98 at 10:30PM. We thought we'd go into the city for a late lunch and/or dinner, would anyone like to join us?

We don't know the city very well having only been there once before so any suggestions on where to eat would be welcome.

Thanks!
