We've never eaten at Sci-Fi, but we really like 50s. We love the atmosphere and the way the CMs interact with their "family members." (Ask for Cousin Jennifer! She's the best!)
I loved my fish sandwich that I ordered for lunch at the beginning of October. My DH had the meatloaf, and he said it wasn't that good.
Back in September 2008, we had fried chicken and roast beef for dinner. Both of those were amazing!
For dessert, I recommend the Boston creme cupcake (Out of this world!!!) or Dad's brownie sundae.
