How much time to allow for TS meal

I was just wondering how much time does it take for a TS meal? We have several planned, but was not sure how much time to plan they take? Will be at WDW the last week in October. Current ADR's are:

The Crystal Palace - 10:30am
50's Prime Time Cafe - 12:30 pm
Tusker House - 1:30pm
Le Cellier - 7:30pm
Be Our Guest - 5pm
Via Napoli - 5:30pm
Mama Melrose F! - 3pm

Thanks!
