Yes there are a few good places in the area.
My younger daughter attends Zesty Spot which is in Pandan Valley
condo.
Emaar
International School has pre-school places at the nursery and Kindergarten. (elder daughter attends there!)
I think the one at Sunset is called Play Days or Happy Days and have heard it is good.
I visited Buttercups Montessori on Grove Lane near Ghim Moh and thought it was excellent.
Pat's School House (one at Pandan Valley) had a long waiting list when I enquired but I have heard it is good.
Hope this is useful.
