One of the few remaining bastions of alternative Soho, The Crobar is a metal bar which attracts a friendly crowd and serves a top selection of beer and whisky
If you like some nice cool beer, portuguese sweets (the once with yellow custard inside) tasty and affordable sandwiches, good strong coffee and football, at all hours. Max Snack Bar is worth checking out.
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 Garden is nestled behind walls and positioned close to the River Thames in Chelsea. The Thames location is no accident as back in 1673 the Worshipful Society of Apothecaries chose their Chelsea village site for its proximity to the river to make the most of its warm air currents. It also gave them a base to moor their barge, allowing them to conduct plant finding expeditions in surrounding areas and to teach their apprentices to identify plants.
