We are a family of five and have eaten at Sci Fi twice. The first time DS9 requested the front seat to himself. He was so into the movie clips and atmosphere of the restaurant, we couldn't get him to turn around and talk to us. We barely got his order out of him, and this is a kid with sooooo much to say. He loved it!
At his request we had lunch there again 3 weeks ago. This time he asked his dad to sit in the front with us. DD13, DD5 and myself sat in the middle seat comfortably. The waiter said we could get some hitchhikers for the back but never did.
Oh, and we really like the food here!
