At Tokyo Dining (not Teppan Edo) but only IF you are sitting next to or near the window. There a few trees and the Japan Gate out by the lake, but you can see most of it.
If you are dining there, you can also go outside to the balcony and watch it, again with just a few trees in your view. You are up on the second floor above the Japan store, so above the crowd. The balcony is a few steps down from the restaurant, so viewing from the window you won't have a view blocked by people's heads. I've seen people just climb the outdoor steps to that balcony too, not dining there. It's not a very large space and can fill up quickly.
