I went there that friday, the entry and all the inflated bounces and slides are absolutely free. There are nice tents installed having sofas and tables to relax and enjoy, all free. There are small eateries, you can have different flavors of Bukhari rice, KFC, pastries, shawrma, parota sandwiches of egg, chicken, etc. and there is a small toys shop too. On top of all, there is a branch of Al-Meera, you don't have to take with you anything.
