I have to disagree..I ate at 50's for lunch and had the best fried chicken..a compliment on fried chicken is worth a lot coming from a southerner trust me!
I also loved the themeing etc..etc.. We went there for lunch and we ate so much we had to go home and take a nap!
Sci-Fi to me was just OK. I LOVED the atmosphere!! It's awesome to sit in the old cars and watch the movies--however--I felt a little gypped. When you walk in you think..this is really a burgers and fries or fancy sandwich kind of atmosphere but they have food like Steak and Shrimp Penne Pasta..to me the food really didn't fit the building and the food was just OK.
I have heard that Sci-Fi's lunch options are a little better though.
