We hired a local "venue" part of community centre where they hold 3 year old activity group. It was perfect and had an outdoor play area as well. A kitchen to heat stuff and some little table and chairs.

It was rather cheap I think was $150 for the day (9-5) and just had to clean up after and sweep floors. We had dips,, cheese, fairy bread, party pies, sausage rolls, pinwheels etc etc.
We had about 50 people there! was busy but ok
