The Hayward Gallery in Southbank center has held my favourite exhibitions in London and each time they are extremely well curated. Definitely a place to visit !
The Barbican has so much to offer! From beautiful architecture, to a conservatory, amazing art, films, music and performances. It is such an exciting and relaxing place to hang out. Even if you don't have a purpose for visiting the Barbican, it's good for just having a tea with a friend.
Best Udon in London, with an exceptional specials board. The head chef Shuko Oda opened the first restaurant in Soho 11 years ago, and they now have restaurants in the City and on Broadway market. Great for kids, our son loves the Mackerel udon.
