A short walk from Oxford Circus tube station, Kaffeine is easily one of the best coffee houses in London. Whenever I'm working in the area I pop in beforehand to kick start my day with a well-made cappuccino.
The closest you can get to Little Italy in the east.
The owners are amazing, the atmosphere is relaxed, the lunches are abundant and homemade.
The cakes are amazing, try Torta Clara (pear and chocolate) for the ultimate bliss.
The Barbican Estate is a residential estate that was built during the 1960s and the 1980s. An icon of Brutalist Architecture the Barbican Estate is an unique and complex real life experiment; a city within a city. The main focal point of the estate is the lake and its neighbouring terrace. High above and behind the terrace is the Barbican Centre, the largest performing arts centre in Europe. I really rate their visual culture exhibitions (for instance, Jean-Michel Basquiat and the Bauhaus) and live concerts (Nils Frahm and Ryoji Ikeda). Love it!
Camping in London? Absolutely! This is one of a few sites which has direct access to Epping Forest from the campsite. Easy to get to by tube, with a fire field and 50 acres to spread out in, this is a great place to recharge your batteries.
