Not the most exciting place inside, but a lovely rooftop area which not all that many people seem to know about, 2 mins walk from Old St station. If it’s packed then The Red Lion is just up the road.
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.
Having spent many years studying there, I have a soft spot for Central Saint Martins, which finally closed in September 2011 when the college relocated to Kings Cross. Despite being such a dive, the old building had such history and character and I grew very fond of its tatty charms. As plans for its take over by Foyles bookshop go ahead, I look forward to having a coffee in the new building's cafe when it re-opens.
