I'm not going to pretend I don't know that this In N Out is officially in Alhambra, because borders don't matter when it comes to great burgers. Anyway, it's barely over the South Pasadena city limits. (And you can smell those fries cooking practically all the way to Garfield Park!)
There's a reason this Southern California institution is so famous: yummy burgers. And if you're wheat intolerant, it's really the only fast food joint in town. There's no hidden gluten in the fries or shakes, and the bunless, lettuce-wrapped protein style Double Double is one of life's great joys. In fact, I wish I had one right now.
