Every time someone posts one of these questions, I must pipe up and say a word for my alma mater, The New England Culinary Institute. As Riverrun said, all culinary schools are good (though I am dubious about J&W), but NECI has the advantages offered by 100% real world training in 8 restaurants, 2 paid internships and a
guaranteed 7:1 student:teacher ratio (not just a stat, no class is allowed to have more than 7 students). The CIA, for all its well-deserved accolades, can't say that; and neither can FCI, ICE or anyone else.
If you're willing to go to Italy, I highly recommend that you take a look at the new
University of Gastronomic Sciences in Pollenzo.
Best of luck!
