Personally - Hakuna Matata for lunch, and Walts for evening (if it's the right time of year for Walt's to be open that late!). Or Inventions for evening to meet characters!
Just to add, if I were going to Inventions, I'd make sure I go hungry as it's not cheap and the food is lovely. If you plan on a CS that day as well, I'd look at maybe sharing a meal between two - the portions aren't huge, although pizzas are big, but you'd then get better value from your TS in Inventions. If that is what you decide to do.
