The many book stores dotted along this strip can provide hours of inspiration. Aside from those selling new books, several specialise in second-hand and antiquarian books.
It's really close to my house and one of my favourite pubs in London! (I even went before it was close to where I lived!) It is London's first cooperatively owned pubs and has lovely events and workshops, exercise classes and great parties, and good beer! It's lovely in the beer garden in the hot summer and equally great in the winter, next to a real fire.
Ever since discovering this area around 6 years ago I still find it a nice area to go for a walk. Beginning at Paddington Basin with a mix of modern architecture which is fantastic to wonder around. Following the canal you go past a few restaurants and underneath a section of the A40 Westway before arriving at Little Venice and beyond.
