I've been throwing around the word "La Lengua" to describe my neighborhood for several months now—ever since I read it on local blog Burrito Justice—and I never fail to get quizzical looks. Never heard of it? Well, it's a new 'hood classification that you'll be hearing a lot more about in the not-so-distant future. La Lengua is characterized as the flat section of the Mission between 24th and 30th Streets, stretching from Mission Street to Guerrero. Most people think of it as Bernal Heights, or, even more bafflingly, the "Outer Mission."
