The first time we ate at Sci-Fi, our youngest was not quite a year old and needed a high chair. We were seated in a car, but it wasn't rows of seats but rather a table for six within the car. The next year, he was old enough for a booster and we were in a regular car. I don't know if it is standard practice to put high chairs in the cars with tables, but that's what happened with us. The boys still enjoyed being in the car and had a great time. One of our favorite restaurants at WDW!
