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)
There's something about this street, probably the fact that it's pedestrianised, that makes it feel like holidays. It also has a solid range of bars (Cafe Kick), restaurants (Berber & Q) and cafes (Brill) so is a good option for all times of the day. They have a quality variety of street food vendors operatin during the day, and fairy lights help it to come alive at night
Appreciate the 'bar hidden away behind a bookcase' thing is pretty naff but the cocktails here are unreal (try the Hot and Cold), and it's inside Milroy's Soho, one of the most legendary spirits stores in the city
