I agree too that it should have been comped, and they should have handled it better. I've dined at CG numerous times, and for celebration dinners. I agree that signature restaurants should deliver a certain caliber of food quality and service.
All I'm saying is the manager asked what iwould do to make him happy, and he said "whatever". I guess what you're saying is, the manager should have comped his meal anyway. Ok, I can see your point. I don't fully agree but that may be because I've been in customer service/guest services myself for so long if I had a problem that was mishandled as such, and then finally a manager came out to rectify it, I would ask for compensation not give a resigned "whatever". But that's me. Maybe that's why I don't have these problems ;-)
Also just wanted to add I'm not trying to crucify the guy for crying out loud. Just looking for this to serve as a learning to us. Other Disers who can learn from this situation.
