**misc-college info**

and most of the time their are many chef's not just one...how do you get information out of them...since i think most of the information i need should be from the manager or the owner. thanks, this really helped me out

**misc-college info**

Ms.Sue told me that the best thing would be to go and interview the chef. but that is only for if i want to work with the chef right. like if i was interested in restaurant management, talking to the owner would be a better choicce.. right?
