There was a Coney Island hot dog joint in the sleazy part of Ft. Wayne years ago and my mother said they made the chili sauce out of the floor sweepings and forbad us to go there. It is where my father always took me after the Komet hockey games! Best dogs in town!
There are two cooking schools here in Cancun. I think that one or both of them might be able to supply advanced year students to work as chefs for tourists. I'm getting the contact info from my friend who knows everyone who's anyone and will let you know what I find out.
A friend of mine was specialties chef at the Fiesta Americana at the time they hosted Miss Universe. He has experience in different styles of cuisine and also caters for special events. If anyone is interested in his services, please e-mail me at: cancunbaseball@hotmail.com
Here is the web site for one of Cancun's cooking schools: Instituto Culinario de CancĂșn - ICCUN http://www.panzafratello.com/index.html My friend who knows the director is traveling so I haven't been able to get personal contact info. But there's a form on the Contact Us page.
