It's great - the food is very good. I'm also a HUGE fan of Napa Rose, which is in the GCH - if that's an option for you at some point during your stay I'd highly recommend it. It's a little more expensive, but I had one of the best meals of my life there....looking forward to a repeat performance on my next trip.
I really enjoyed the fixed price dinner. The steak wasn't too large which was great for me, and the salad was quite good. The dessert was an apple dumpling type tart, and it was wonderful. There really was no other way to get that much food at that restaurant unless you did the fixed price dinner. (You also get to eat some pretty great bread.)
