Probably known as the financial district in London, The City is an area that never fails to surprise me. It's full of bankers in suits ready to splash the cash on an after-work session (at Dirty Martini or Coq d'Argent, obvs) during the week and yet desert on weekends. Quite fun to envision! And kind of a pity, there are many cool places around the area that are as enjoyable on a weekend.
I also find it very interesting that in less than a 2km to your right is Shoreditch, which could not be more different: creatives, artists, and fashion designers who could care less about splashing the cash or wearing a suit (they meticulously have though of it but they don't want you to know, that kewl); and about 3km to your left is the West End. How amazing is that? That's one of the beauties of London. DIVERSITY, PEEPS!
In any case, in this little area that we call The City there is an oasis from the 14th century: Leadenhall Market. I discovered it during one of my lunch breaks when I was working nearby and I instantly fell in love with it. The architecture of this arcade is remarkable and it stands on where it once was the centre of Roman London. Curated with selective shops, cheesemongers, butchers and florists, this place remains a hidden gem for many. Go there during the week to see the business buzz or during the weekend if you want to get a beautiful (and deserted) picture.
Either way, it's a must! Do not miss it.
