Relaxed with character. Tiny garden at the back overlooked by Waterloo train station. Not sure if mother cat still lives there. Nice to go with friends or alone. Books. Good for a coffee and cake or a bottle of beer. Spiral staircase down to basement. One loo serves the place - tip - lock the door, don't just rely on the curtain and save an awkward encounter.

Being down on the underground can be quite stressful and draining, but if you have the chance to look up and into the details that has gone into the tiling of the platforms and stations you might start to see some beauty down there. A lot of stations has bespoke tiles and decorations, almost a century old.
Bethnal Green station is one of a handful in London to have been given a very specific additional decoration to the classic cream tiles and name strip. Easy to miss, but dotted around the station are a series of tiles with raised motifs on them, representing aspects of London and places that the Underground visited.
Or for typographers: check the type on Hampstead station or Holloway Road for some inspiration.
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...
