I'd suggest doing the Fantasmic package with one of the three restaurants. It is only one TS credit and you get an appetizer, meal, and dessert. It also gives you prime seating for the show without needing to waste a fastpass on it. I went to Mama Melrose and although not the best meal I've had, it was a lot of food and it was nice knowing I didn't need to rush to the show to get a good seat later that night.
