Park or Similar for Family Day Picnic (Manila)

Hi everyone - I am organising a family day picnic for my work & what a nightmare!!

Makati doesn't allow group bookings....which is a shame as the park in Salcedo woulda been great.

I'm looking Makati/Fort area. We want to have catered food & play games (there will be lots of children).

We won't be venturing out to Quezon City or anywhere that far.

All help greatly received, even an indoor venue ☺️

Thanks in advance!!
