Can I have your best ideas for a day in London to impress a friend(shallow alert!)-needs cultural and show off brownie points

[Finbar]

Are meeting late morning. I need to concoct a day that when she goes back overseas she can say "and Finbar knew this amazing place..." (ha!)

Lunch?

Then am thinking one of the galleries or museums plus afternoon tea (maybe too much food?!)

Have done the Athenaeum for tea and wondered if there was anywhere else interesting and different.

Shallow? - yes... But work with me

The Delauney or The Wolseley for brunch

Claridges or Browns for Afternoon tea

Matinee of Midsummer Nights Dream ( David Walliams) at Noel Coward Theatre >

Oh I like that!
Forgot to say -its a Sunday though

Lunch at the national portrait gallery restaurant with views of trafalgar sq. lovely.

Tom's kitchen or Deli at Somerset House ? ( pity it is not Christmas time, ice rink is stunning)

Not sure if it is still going, but the Belvedere in the middle of Holland Park ( actual park) used to be lovely.

Like wise Julie's Holland Park.

You also can't go far wrong with The Ivy - an oldie but still a goodie.

If you're going to Somerset house go to the Courtauld gallery
