Yes they are.
Children are welcome in the whole restaurant with an adult, and I'm fairly sure teens are welcome in the "back" or main diningroom without one.
Yes. No alcohol is served for them. They have Colas in short bottles or other drinks age appropriate. Enjoy.
As long as an adult is with them i believe. We had a 13 year old with our TOUR group and it wasn't a problem. Maybe be diff without a group
