An obvious choice but no 'best of London' list is complete without the Barbican

Go check out this very untypical gallery in the underground. You don't need a ticket and it does only take you a second to soak in the art displayed.

Being down on the underground can be quite stressful and draining, but if you have the chance to look up and into the details that has gone into the tiling of the platforms and stations you might start to see some beauty down there. A lot of stations has bespoke tiles and decorations, almost a century old. Bethnal Green station is one of a handful in London to have been given a very specific additional decoration to the classic cream tiles and name strip. Easy to miss, but dotted around the station are a series of tiles with raised motifs on them, representing aspects of London and places that the Underground visited. Or for typographers: check the type on Hampstead station or Holloway Road for some inspiration.

If you want to eat a good cake this is the place! They have so many cakes to choose from but the best one is the white chocolate cheesecake. 

The oldest public art gallery in London also is my local gallery in my neighbourhood. Opposite to the Dulwich Park where I walked with my puppy regularly. They have great collections of Dutch paintings as well. My husband found the original Dutch painting of the print at his home he was growing up with.
