I would pick Prime Time Café. Sci-Fi is dark-ish with old B-movie trailers playing -- not really too scary, but might frighten a small child. Also, the seating is mostly in rows of 2, like front seat/back seat of a car. I think the food at PTC is pretty good homestyle cooking - meatloaf, pot roast, fried chicken and the PB&J milkshakes are delicious! I think there is more food that will please a big group at PTC. Also, the atmosphere is fun if you have a server who is really into character and makes the parents finish their green beans and such.
