We were just there last week and had the character lunch buffet at Hollywood & Vine. Honestly, we were quite disappointed with the food. But we LOVED the character interaction. They did have the standard mac n cheese and chicken nuggets for kids. Some of the things that I tried were a chicken alfredo something (tasted fishy???), some chicken with a creamy type topping ok, but not that good), some polenta thing (yuck, but I've never had polenta before), garlic mashed potatoes (pretty good), ceasar salad (ok but soggy and overpowering anchovies), a tomato pasta thing (not that good). There was however an orange pineapple chicken breast that was really good. There was also an ice cream bar with toppings and a few dessert items like cookies, cheesecake, brownies. I won't say it was "bad" but not good enough for us to go back or recommend it to others. Unless you are really looking for that character interaction, the food can be tolerated. Though most of the characters we saw there were near Playhouse Disney Live and the animation building.
Sorry for the length but hopefully it will be helpful.
