Any fast food place, just ask around some companies don't follow the age limit on hiring. I got hired to work at a Baquet Hall when I was in 9th grade so I had to be 15 years at the time. So you just gotta ask around, and not assume that you would have to be 18 yrs to work at a certain place.
Restaurants are perfect! I've worked in about three since I was fourteen and it's the easiest thing to do!
