Century Park is quite nice for families. You’ve got the park and the Kerry Centre for shopping, a nice evening out, and some half decent restaurants.
Thumb Plaza area would probably be my first choice for Pudong. It has a Carrefour and some more expat style bars and places to eat.
By far the best place for families in Pudong is JinQiao, great housing, and a great number of expat families and expat family activities going on there.
