Does the university have a program in hospitality? If so, the
faculty will probably have the experience you need. Otherwise,
you may want to contact some of the schools (Johnson & Wales,
Colorado Culinary Arts, Food Network, etc) about it.

It's a business -- you need a business plan, etc.

You may also want to contact some of the more successful
restaurants at airports. These shops really do a very
large catering business for the bizjets, etc. in addition to
the walk-in crowd. "Perfect Landing" at APA is a great
example. They used to be open only for breakfast & lunch but
last year also opened for dinner (usually only the locals will
be there for dinner). Booming business.

If the school has a hotel & restaurant program, then they'll
be delighted to use you as an internship source! Experience
for the students, affordable labor for you.
