There are two sets of barbecues a short distance from each other along the path that bisects the picnic huts. Although crowded on the weekends, people are always accommodating and will share precious hot-plate space ensuring everyone gets fed.
Bronte is favoured universally. This can be seen in the moiety of travellers and locals comprising the crowd. If you are keen for some more adult fun, it is best to head down in the late afternoon. By this time most of the families are headed off home and big games of soccer are not unusual.
It is free to use the barbecues and it does not cost to use the facilities. After sundown, the toilets are locked though and the nearest ones are up a large hill. There are only cafes and restaurants nearby so don't forget to grab snags and sunscreen from Clovelly Shops, Charing Cross or Bondi Junction before you arrive at the beach.
Although signs proclaim drinking is not permitted at the picnic area or beach, this rule is not enforced at the picnic area. Patrols regularly go through the grounds. The few times I have seen them enforce this was when it was being abused.
There are also lots of local dogs that play around the picnic area. If you aren't comfortable with having he occasional dog run off with one of your sausages, maybe select another beach.
