London Recommendations?

[wondersofwine]

On one trip to London I ate mostly at foreign restaurants in the theater district--Greek, Chinese--or pub food. But on a Saturday night I had a good roast beef and Yorkshire pudding meal at a noted chop house. I was thinking to myself "finally a good English restaurant" and asked the waiter if they would be open the next day on Sunday. "No," he said, "We all go to church on Sunday." "And we all go hungry!" I replied. So he had the carver come back and give me a second helping of roast beef so that I wouldn't go hungry the next day.
P.S. On my most recent trip to London we saw "Beauty and the Beast," a revival of a musical, and "The Importance of Being Earnest" with Patricia Routledge (Hyacinth in PBS series "Keeping Up Appearances"). Couldn't get tickets to "Lion King." I have seen Maggie Smith live but not the others named above.
