Short answer - yes!
Long answer - it depends if it gets categorized correctly as restaurant instead of travel/entertainment. All our WDW restaurants from 2 years ago got categorized as travel/entertainment. I live chatted and was told that I would get a credit. Well, I never saw the credit and I forgot to follow-up. But thanks to your post I was reminded and just live chatted again, was told I would see the credit on my next statement. This time I will remember to follow-up! The rep mentioned that they've fixed this issue, so hopefully you will just automatically get the 5%.
