The only other place I can think of get to waffles is the Minnie Mouse & Friends Breakfast at Carnation Plaza.
I have a feeling I know the answer, but the famous Potato Soup is only available at the Carnation isn't it? - it won't be available elsewhere whilst Carnation is being worked on?
Oh for corn's sake! How long will it be closed? Carnation Cafe is my favorite and we will be there next month.
Outside of the park, I believe they serve Mickey waffles of some sort at White Water Snacks in the GCH. You can also order them off the menu at Storyteller's breakfast. I don't know if strawberries are a topping option at either of these places.
