Kaffeine serves amazing coffee. The sign outside states 'We serve the only authentic flat whites in London'. You could call them cocky for saying this, Lantana is after all only a moments walk away, but when the coffee hits your palette you'll agree; they are most deffinately up there with the crema of the crop. They are kinda wonderful. Refreshingly they don't overcharge either - The coffee's are all around the £2 mark and the perfectly moist and flavoursome muffins are only £1.50. I'll be visiting again.
