We have been taking our DS to the Canberra Southern Cross Yacht Club on Alexandrina Drive in Yarralumla. Ask for a table in the restaurant as this is a little bit apart from the bar area. And mention that you have a young child so will need a high chair, too. A table near one of the many windows always proved to be a great distraction for our DS as the place overlooks the lake (lots of activity).
DS was crawling and the staff didn't mind at all. We did keep an eye on him but there was plenty of room. It shouldn't be too busy tomorrow so your child shouldn't be in the way of any of the patrons there.
And the food is very delicious ... make sure you leave room for sweets.

Enjoy!
Cheers,
Helen.
