I would pick 50's PT! We love that place. They have a sampler plate that you get a little of all their best meals (fried chicken, pot roast, and meatloaf). I am in love with their pot roast!!! We have been there 4 times now and have never had a bad meal lunch or dinner. We always tell them upon checkin that we want a "FUN" waiter or waitress. Our 2 fav were Tara and Richard. But... We always make it appoint to play back... And that is probably why we always have great interaction.
We haven't tried Sci Fi because I have heard not so great things about the menu.
