Not the most exciting place inside, but a lovely rooftop area which not all that many people seem to know about, 2 mins walk from Old St station. If it’s packed then The Red Lion is just up the road.
Eccentric and surprising house and museum of architect Sir John Soane. Mostly unchanged since his death over 180 years ago, it is full of atmosphere. Also have spotlit, late night openings.
This vegetarian south Indian is a bit of a hidden gem, good curry friendly staff very reasonable with bring your own booze doesn’t get much better than that.
South London is largely underrated considering at times it's a treasure chest of gems; Battersea Park is one of those big sparkly ones. An interesting mix of faultlessly pruned gardens, displaced architecture, shape, form and colour generate a delightfully influential weekend stroll. With views of the almighty Battersea Power Station and the river dividing you from the Chelsea Embankment.
