We really like Rowdy Rascals at Jindalee Homemaker centre. I have found the cafe to have a good assortment of food (with many healthier options for kids, unlike one other playcentre which had 1 choice - an apple
), the toilets are clean, play area is large, and there is ample seating. (we generally book so we can be close to the infant area if we have infants).
We are also BIG Rocks Riveside fans. The waterplay area is great (but abit chilly at the moment).
