Hi! Really excited you are so into cooking. I think the best first job is should be at a place you like to go to and is convenient for you. Most restaurants are pretty willing to hire part time help, especially in the kitchen. I wouldn't worry to much about whether this first job is putting you on the path to be a chef. It's much more important to get a little experience and see if you really like cooking professionally. Cooking can be a ton of fun and high energy around it but it's super hard work too. They make it look easy on TV!
