I'm going to be in London for a weekend (May23) and am looking for a memorable dining experience that won't break the bank (<50 pounds without drinks). For an example, I always recommend New York city visitors have Sunday brunch in the Blue Room at the top of the Rockefeller Center. It's a total "Wow!" experience.

I've posted a similar query in the U.K. and Ireland forum, but came up empty handed. I'm hoping the subject title will perk the interests of international foodies.

Thanks in advance!
