St Paul's Cathedral, St Paul, London
The third part of the trip starts from this majestic building rebuilt after the Great Fire in 17th century, St Paul's Cathedral. It is worth seeing the inside of St Paul's to completely witness its magnificence, however, if you would rather spend your £16 for something else, seeing outside of it will do as well.
A completely different architectural texture is just about 10 minutes walk from St Paul's Cathedral and it is a building complex called The Barbican Estate. A perfect embodiment of brutalist architecture, Barbican is a post-war built Orwellian-esque residential complex. It is seriously worth having a look at this concrete giant because it is one of a kind.

I'd recommend an additional architecture tour for all architecture fans out there as London is the base of some of the most remarkable buildings in the world.
Moving onto: Not-so-hipster-anymore Areas
For all outdoors market, vintage, design and all-things-creative lovers out there, Old Spitalfields is your starting point (runner-ups are in Brick Lane, Camden and Hackney). You are now closer to where Central London ends and East London begins. Old Spitalfields is close to Liverpool Street where you will see many people in suits but as you step away from Old Spitalfields, the faces and clothes people wear are going to change.
Old Spitalfields is famous for its market and restaurants but the real gems are Shoreditch and Brick Lane. They are the complete hipster package with themed cafés, amazing street art, quirky pubs and secret bars as well as some good music venues such as Blues Kitchen, Village Underground, Hoxton Square Bar & Kitchen and Old Blue Last.
You can find many rooftop, underground or secret cocktail bars and enjoy delicious drinks. This is a creative and young area for a slightly more expensive night out that's bound to be exciting. Even during the day, it acts as an open air art gallery with many street art works colouring the buildings and provides you with many Instagram post opportunities.
I would also suggest you to pay attention to the signatures and see how many similar works you can recognise from the same artist.
