I agree with AGP423 too about value for money. If you're in the US or Europe there are far easier ways to have a great dining experience.
On the other hand some things are fun to do just for the heck of it.
Not sure what travelling there involves but I figure, if your disposable lets you do it, then go ahead.
It's only a short flight for me so I opted in. It has the added benefit of time in Tokyo to do some additional eating.
