Is there a restaurant inside the building? Can you bring food?

There is a restaurant, you can NOT enter food.

I think you can buy food at the basement. Very very expensive. I suggest eat a good meal before entry.

I don't think it can be carried. If you have a restaurant

You can not eat, right now, there is a restaurant in the upper part of the building. Sometimes there is some audition in the afternoon and you can listen to music while you have a drink and eat something.
