Found this interesting tonight at Izumi so figured I'd share. Previously with the ultimate dining, you'd get 1 small plate and 2 large plates. Those two large plates consisted of 8 pieces of sushi each. It was too much food.
Tonight, with ultimate dining, you still get 1small plate and 2 large however each large plate is only 4 pieces now. I asked when it changed and he said about a month ago, but it only applies to the ultimate dining package. If you order and pay a la cart, you still get the 8 pieces for each large plate.
This is on Odyssey. 4 is still plenty but another cost cut for their already increased dining package prices.
