We ate at both on our trip ... I thought both had good food. Totally different though ... 50s is really up-beat atmosphere, home-style food (chicken, meatloaf, pot roast, etc) -- and great desserts. MM took a LONG time for us to get our food, but was equally good. If you're going to 50s, be prepared for the joking around ... and any punishment you may receive (one man had to stand up and sing "I'm a little teapot" to the entire place).
