Definitely 50's PT. Everyone in the group will love the atmosphere, not to mention, the good "down home" cooking. Have a wonderful trip. You have quite the grand gathering going on vacation.
Haven't been to MM, but LOVE 50s Primetime Cafe! The pot roast was delicious and my daughter got a huge kick out of the waitress playing 'airplane' with me for not eating all my veggies.
oh boy. we have ADRs for both MM and 50's. but, i see everyone has different opinions on both. I'm not going to worry too much. we've eaten at sci-fi and thought the atmosphere was cool but the food was eh. I hope we enjoy both.
