I took the roasting and grilling class about a year ago and it was great fun! Your ingredients are already on a tray which the students bring you. 1/2 classroom then cooking and then .. . dining on what your group prepares!
I would love to do the five day boot camp; the only thing that sto[s me is the expense. BTW, it's in Hyde Park, not NYC. Martha Rose Shulman wrote an entertaining book on the boot camp experience.
Nope, but they used to send their students over to my college dining hall to be guest chefs occasionally. You knew it was a CIA day if you walked in the dining hall to see Duck Confit with Raspberry Coulis or some such thing on the menu. ;-) I've never taken a CIA class, but if they can make industrial dining hall ingredients taste that good, it's probably worth it.
