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.
You might think the Tate Britain is the less interesting of the two London outposts: full of crusty oil paintings and pensioners on day-trips, but you’d be wrong. Not only is the building a delicious warren of interconnecting rooms, each more beautiful than the last, but it also houses a collection of pre-Raphelite works that has me in tears of awe every time I swing by.
