We have bodegas and trucks, for a very reasonable price, although the trucks cost less, I suppose because of less overhead. If anyone's never had homemade tortillas, I recommend them. In the bodegas, they usually have a machine, similar to the wringer on the antique wringer washers so they're thin and more uniform, but hand made masa tortillas are divine, especially topped with avocado and queso fresco.
It's less a function of not having decent Mexican food and more a function of both food trucks and the concept of "walking distance" not really being things in most of the metro area.
