Somebody Help Me: Where To Eat in London’s West End

Hello, friends and foodies. I’m in London for the night before I leave for Paris tomorrow afternoon. I’m staying at the Langham, and I need a decently priced spot for dinner nearish the hotel. As you can imagine, we’re pretty beat, but we’re going to hang in there! I’m off to Fortnum & Mason right now (can’t wait), but I’d like a quiet little bistro or cafe for dinner. Any suggestions? (James Dean, there’s a message from me in your inbox on FB.)
