The Strand Dining Rooms. I don't remember much about this meal. We were seated right away, inside, without reservations on a Friday evening around 6 pm. We were seated off to the right as you entered so I didn't see much of the restaurant. We made our dinner selections quickly because we wanted time to visit The National Gallery before it closed at 9 pm (it's open late on Fridays).
We liked, but didn't love, The Strand, but it's a decent choice if you're a tourist looking for above average food. Plus, it's in the Trafalgar Square area, so very close to lots of stuff.
