Hi there Crystal! We have Ratatouille movie fans here in our family too!
I called
Les Chefs de France directly at (407) 827 5032 to confirm Chef Remy's typical appearance times and was informed he can be seen 5 afternoons a week at: 12:30, 1:40, 2:50 and 5:20. On Sundays and Mondays, Remy spends time at home with his colony thinking up fresh, inspired dishes to prepare at work.
Since March 30th is a Friday, you should be able to experience this delightful rodent in action. However, I would recommend double-checking the Times Guide when you enter Epcot and perhaps arriving a little early for your advanced dining reservation so that you're seated in plenty of time to catch the performance.
Thanks
for taking the time to visit us at the Walt Disney World Moms Panel and
feel free to send more questions our way in the days leading up to your
trip! May your Disney vacation be practically perfect in every way!
