It's not that the food at CG is bad, it just lacks flavor. It wasn't always this way, but it seems that over the last few visits there, the food has gotten duller and duller. Also, the sushi that everyone raves about is overpriced and nothing special (if you want sushi while in Disney head to Kimonos at the Swan, much better selection, quality and prices IMO). Actually, the only thing that was tastey on our visit to CG in October was the candied bacon ice cream that came with the apple bread pudding (the apple bread pudding wasn't all that great, the ice cream made the dish).
As for 'Ohana and Narcoossee's, I personally don't get how people leave those restaurants happy. 'Ohana has consistantly given us the worst service on property. The pot stickers, wings and noodles all taste like something out of the frozen foods section of any Supermarket and the meats/poultry are dry and tasteless. Again, didn't always used to be this way but as the popularity grew the quality of everything else got worse and worse. This is not to even mention that we have grown to detest the emcee woman and how loud and obnoxious and intrusive on the meal she is. And the fact that they still consider Narcoossee's a "Signature" restaurant is laughable. Everything about the restaurant is subpar from food to service to the atmosphere.
