I've been there multiple times (to buy things that I've had my eyes on forever), but it's a really small place for a mall, so while I think it's cool to go there and poke around, it's not worth it to make a whole trip just for NEW PEOPLE. But since Kintetsu mall (the one with Kinokuniya in it) is right across the street, go there too. There are multiple sections of the mall, but the one with Kinokuniya is the most interesting/worth your time. The crepes are good--there are two places, but I like Sophie's Crepes more. It's right next to Kinokuniya so you can't miss it.
newpeopleworld[dot]com should have some info on the NEW PEOPLE building (in case you hadn't seen it yet)
