We picked Sci Fi. When it came down to it, the menu looks better to DH and I at Sci Fi. We are not really a Pot Roast/Fried Chicken kind of family. The atmosphere seems fun too. Based on my review-reading, it looks like Sci Fi is fine if you get burgers or the Reuben or the chicken sandwich with shakes and fries. My expectations are fairly low for the food - those types of items can easily be good.
We'll be there in 10 days and I'll post my thoughts when I return! Oh and we think Sci Fi lunch is a good OOP choice as the burgers/reuben/chicken sandwich are not too expensive.
