Rays Reef at Royal Plaza, Al Saad Street. Great venue. They have soft play area for little ones, a larger soft play area with huge slides and climbing for older ones. A ball pool shooting area,, ball pool, video games and an area for arts and crafts and painting and stuff like that. I think they charge 40QR for each child but that includes a meal for each child aswell. plus they have underground parking and the staff take good care of the kids so you might be able to relax too! Ha, ha.
