I took my little girl to Splodge Play Cafe on Diagonal Road in Marion this weekend. It is brilliant. $5 and under 3's free. You get a craft pack as part of your $5 and once in the cafe it shows you how to make the craft of the week with your pack.
They have 4 different rooms i think, messy play with paints (you can paint on the walls) a chalk board the entire length of the wall, craft materials, playdough, tv with movie of the day, outside play, sensory play, dress up's - you name it they have got it! All smocks etc provided. Kids nursery rhymes on it the background, so sweet for the kids!
They also have a small baby section at the front too with some baby toys.
There is a 'normal' cafe in there too where you can order lunches, teas, coffees, juices, cakes etc.
Overall a great cheap morning out! They have a website and a facebook page, just check the facebook page or call before you go as they have a lot of kindy groups and parties so arn't open to the general public all the time!
