Slightly biased as this is where I live, but Stoke Newington is great place to spend lazy saturday / sunday afternoons getting sloshed with friends. There are 10 + pubs within walking distance who all are great places for one reason or another. I'll pick out the White Hart for its huge beer garden...
The outside displays are mysterious and inviting and reveal little to the magic that this place inhabits. Fantastic presentation and exhibition of garments and design pieces. It's an exhibition experience like no other. Not to mention it being the place to get most loving shirts in town. Don't forget to stop by the Rose Bakery for coffee and lunch. A hidden gem.
Walthamstow Wetlands are London's largest urban wetland nature reserve, home to many wildlife species. Only 15min from central London. The cafe is open daily for breakfast, lunch and afternoon tea.
In between soho and covent garden. There ares lots of great independent shops on this street. Dover bookshop, magma, super superficial and Mint to name a few. Also if you want a cheap lunch on your work break Cafe No.1 is amazing. £2.50 jacket potatoes with cheese and beans.
