I love the Brixton markets, they are about as far from the food aisle of any multi national supermarket as you can imagine. One minute you can be in Thailand, then Jamaica via Turkey the next. Franco Manco is pretty busy, but it’s very special to me.
The Barbican is worth visiting for it's brutalist architecture alone. The concert programming is really diverse; it's home to the BBC Syphony Orchestra, but you'll also find bands like the Dirty Projectors and the National amongst the classical and contemporary composer line up. Plenty of art, dance and theatre too, however, the Conservatory is the real gem that's not to be missed.
This is my new local cafe. Healthy food, lovely people and great atmosphere. My favourites are the kyuri cleanse juice, the Avodon and the Joy's salad. Great place for meetings too.
Getting lost is an age old suggestion but a good one. Put away your cell phone or your A-Z and just wander around. I still do this regularly even though Ive lived here for nearly 10 years. London is a big city and it drip feeds you its secrets sometimes. You will come across things you wouldn't usually, in amongst the Starbucks and pret a mange there are some amazing sights. Just 'being' somewhere is a great experience and one no guide book can help you find.
