A great place to start the day if you are in South London is Federation Coffee in Brixton Village. The food is great and so is the coffee. This is a very chilled place where you can get both and indoor and outdoor experience (even though the whole place is under the Village roof).
As preposterous as this sounds I think there are few ills that can’t be cured by sitting lazily on a stack of rugs in Liberty and allowing the patterns to wash over you in a warm, and slightly itchy, haze. If you don’t believe me try it. The second you step off the main shopping area the sound and lights dim, the rugs beg to be touched, and all your worries seem to disappear.
