Family Lounge at level C with changing table station and breastfeeding private spaces. Also some games for toddlers
Westfield San Francisco just moved the fake grass lounge area from the dark corner to under the dome (4th floor by M.Y.China). It's a great place to take a break with the little ones. And since moving it, it's had a steady stream of parents and kids playing there. What's hard to see in the picture is the oversized blocks/dominos to play with on the middle grass section.
