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.
I love the George and Dragon Public House. Cluttered deco of silly artifacts and memorabilia and slightly scuzzy around the edges. Great drinking characters, DJs and The White Cubicle gallery in the ladies toilets is difficult to beat.
Behind Markfield Beam Engine is the River Lee which travels from the Chiltern Hills all the way to the Thames via Tottenham Hale. There is a special light along this stretch of the river possibly due to there being about 10 massive reservoirs behind the levee on the other side of the river, offering an amazing sense of space. A great place to walk, cycle and feed the ducks, swans, geese and coots.
Founded in 1828 the museum houses around 67,000 specimens many of which are now extinct or endangered. My favorite is the skull of a Bottlenose Whale from 1860.
