Any Places that allow mixed genders?

We're a group of teens(around 10 people).Is there anywhere we can hangout that isn't a compound?

1. DQ (but I'm not sure that the guard will let a group of teens to go there)
2. Rent a villa for a day.

There are some places near AWAHA dist North Riyadh 
It's wide area and have gate's and you can hangout there free . Many times I saw teens groups hanging there .
