I have a question about a Culinary Arts school in California??

I'm considering attending the Kitchen Academy in Hollywood and was wondering if any graduates or people familiar with the school can give me information on the school. Basically is the Culinary arts diploma program worth the $20,000? They say they have recently linked with the Cordon bleu (California school for culinary arts) and I don't know if that means they now have a better reputation or not. Does the school provide a quality education?
