Summer jobs for 15-year-old in Berkeley?

Hi there, 

I am looking for paid summer jobs or opportunities for my son, who will be a rising 10th grader this summer. He had a great experience working at a camp through YouthWorks last summer and is hoping to do more this year. Can you recommend any camps/programs/stores/restaurants/etc. that will consider hiring a 15-year-old with a resume and recommendations? 

Thank you! -- Christopher
