To each his own - I've had great experiences at Kouzzina. My family of 12 went down last year around this time, and we struggled at a lot of restaurants that just couldn't handle a party that large (even though they took our ADR!) But Kouzzina was great - they got us in and seated on time, they were extremely attentive, and the atmosphere was great for family bonding. Also, we loved the food.
Then my mom, dad, husband and I went again in May to celebrate my husband and I (finally!) graduating college after 8 years of part time studies, and when they announced our celebration to the room, instead of just the normal Opa! the whole room cheered for us and came over and congratulated us - it made us feel really special about our accomplishment. And again, the food was fantastic.
I've had bad experiences every time I've eaten at California Grill, though, and I know plenty of people swear by their experiences there - so to each his own
The reason it matters, though, is that a lot of people booked these signature dinners with the sole intent of seeing her, and Disney is being very elusive as to whether or not she is actually going to be there. I love my Kouzzina meal, but as previously mentioned I can do the chef's table for cheaper - I'm paying the premium to meet her. I talked to a friend that had the signature dinner on the 30th booked, and she got a call that it was cancelled. I've tried to find out 3 times now if mine is cancelled and every CM I've talked to thinks I'm completely crazy and tells me only the 28th is cancelled, despite many reports to the contrary. For that much money, you'd think they would be a little better about disseminating information.
