Covenant House New Orleans. They offer shelter, clothing, food, whatever is needed to homeless teens and young adults. Before Katrina they even had a drop-in center where kids could stop by and pick up supplies or see a nurse. They also offer free classes on everything from basic health to balancing a checkbook to applying for a job, and if you take a class you get a free lunch from the corner store. I have SO many friends who got off the streets and made something of their lives largely because of Covenant House.
