I find myself writing posts about burritos about once a month; they really are one of the latest street foods to take London by storm. I visited Chilango for the first time this week and was very impressed with the standard of the food. It's not the cheapest burrito around (expect to pay over a fiver for a burrito and about two quid for a taco) but the steak filling was very tender and some of the tastiest I've had in a long time. The ordering process reminds me of a Subway (you pick and choose the type of beans, relish, salsa etc.) and for the carb-conscious, you can have a salad or order yours 'desnudo' (i.e. naked). My only disappointment was the lack of side dishes; only tortilla chips are available, which are extra. On the plus side, the Upper Street branch also has a reasonable seating area, which makes a change from being stood on a street corner while you chomp your way through what can often be quite a messy experience.
