We've already missed Creperie Nicolas, dammit, so get your asses down to The Rye, Peckham, SE15 3NX this week for other street food stalls.
I, for one, plan on stuffing my face with at least a few tacos, a load of chocolate, more than 3 hot dogs and the rest of it. You should too. (Unless you're a vegan. I suspect there's not much there for you.)
