Certainly the grooviest hairdresser in Paris. Great cut, friendly staff, good music. Not cheap, but worth it for the experience. There are three branches: 7, Boulevard Beaumarchais, just next to Bastille metro and my local, plus at 68 Quai Jemmapes and 53 Rue Monge. One tip - they don't take cards, only cash or cheques and rather trustingly let me leave the salon to go to the cash point.
