We never found it weird. I love Sci-fi and it is my opinion that no other Disney restaurant comes close to Sci-Fi in terms of theming. You will likely all have one car and sit two to a row, so you will see the back of the heads of those in front of you. However, our party mostly watches the movies on the screen, anyway, and don't talk as much as we do at other restaurants. They have cute little cartoons, fun trailers from really cheesy sci-fi movies of the 50's, and commercials from drive ins during that time (remember the scene in Greese where Danny is singing about being stranded at the drive in while that hot dog does flips in the background? That's one of the commercials). So our family never really thought it was odd or awkward - it just really fits with the theme and that theme is what keeps us coming back each trip.
