Sci-Fi is not really the place to hold an ealborate conversaion. It is dark and the restaurant is set up like a drive-in theatre with movie screen playing the entire time. Even if you are a family of four, two people are in the front and two people are in the back. My DF and hardly talk when we go there because his eyes are glued to the screen, but is still a ton of fun. I think if you want to have fun and don't mind splitting up for one meal, it is def. worth it. Love the food and the atmosphere.
Oh and BTW, my DF and I are very tall and slender and I would NOT want a person between us while eating, so I have no idea why the cast member said 6 to a car.
