I just wish we had one around (Boston resp. Providence) esp. in the wintertime...always stuck at museums, playdates, or at home. I raise two kids by myself and both hate chuck e cheese and I am sick of Mc. Don with indoor jungle gym. And at jumpolin places no food is served.
By the time the first G N H opens around here my kids will be to old but I'll still go there (alone)

, have a beer and sit back and relax

and think about the good old times (both, investment and parenting -wise)
