The robot show was great but we have been quite disappointed with the restaurant.
When booking this activity, we sent an inquiry for the vegeterian meal. We have never received any comment on that from either Viator or the provider itself but when we came to the restaurant we were served a meat and fish set with just a small salad on the side. Staff spoke, of course, Japanese only so when we tried to ask if they have ever received our inquiry about vegeterian meal, the waiter said that it's a set that can be only served as it is.
It could have been nice to get a follow-up when it's not possible to order a vegeterian option and not to pay for a meal you can't eat.
So, vegeterians, be aware when you book this activity combination.
Otherwise, the show itself was fun and is definitely recommended.
