I was in the Kensington market for pedestrian Sunday when I came across this stall. Reminded me of Beavertails so I decided to go check it out. They had churros and you can have them plain as it or with filling. The options for fillings are strawberry jam, caramel or chocolate. I recommend the strawberry or caramel (the chocolate is not very tasty). My only complaint was that when the guy was filling the churros, it didn't always go into the churros and was just on the surface.
Great street food though!
