A great place to wander get lost and and escape the city.

French Bistro style restaurant. Cozy atmosphere 

The closest you can get to Little Italy in the east. The owners are amazing, the atmosphere is relaxed, the lunches are abundant and homemade. The cakes are amazing, try Torta Clara (pear and chocolate) for the ultimate bliss.

I personally love photo arts and this gallery puts on some amazing exhibitions by the best artists, such as Vivane Sassen and Gregory Crewdson. The Gallerys’ six-storey space is located right by Oxford Street, so if you are doing some shopping in London, you might as well stop by this gallery. The upper floors consist of two new galleries, while the ground floor hosts a nice café/restaurant. Together with the print sales, the bookstore occupies the basement of the building. I can spend hours just looking at the books, how it is designed, bound, as well as the prints for sale. You can buy all kinds of film; medium format to polaroid film at the store. After some hours at this gallery you just want to go home and start making some photography! 

The walk along the South Bank from Westminster to Tower Bridge will take you past a plethora or interesting sights and cultural hotspots. There's always something interesting going on too.
