The V and A houses a public collection of prints and drawings of every kind imagineable from old master drawings to photographs, playing cards, fashion plates and wallpapers. You have to select what you want to see from the collection http://collections.vam.ac.uk/and book in advance. The behind-the-scenes route up to the study room of v and a is a treat alone (pictured)

Morito is a few doors down from it's well know sister restaurant Moro. This not long open tapas restaurant feels like it could be in a little back street in Barcelona. The food is great, and it has a buzzy but relaxed atmosphere. You might need to wait a little while for the table, but I promise it's worth it.

best family run sushi i can find in London.  Not flashy but that not the point.  Its a small honest run place.  Its great.

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

Nice coffee around Soho. Very good vibes and nice space.
