On the ground floor, by the food court, there's a kiddies play area (I think it's suitable for kids up to the age of 4) which is small and only has 1 exit, so while you're sitting at a table enjoying that much needed hot chocolate (or coffee), you won't miss them running away to go see the fresh fish at the seafood shop.
Now that winter is on it's way, it's also a good way to get out of the house and entertain the kids whilst not having to spend too much money. I have noticed since living on the northern beaches, everyone has money for a hot drink, even if it takes scrounging around for some loose change. At the Donut King in the food court, they have a great special; you get two free hot fresh doughnuts with your choice of hot drink - what a deal! I'm making great use of the VIP card and have already managed to clip my way up to 1 free drink.
At this specific Donut King, they also sell 50c ice-cream cones - just so you know for summer. Yum!
