Here's the Mall Restaurant. Whenever my Sims visit the Mall, they can have dinner as a family or socialize with folks they don't know. When I send a Sim with high cooking skills to the Mall, I have him or her cook up a great meal for everyone. Otherwise, individual Sims just make their own meals when they're hungry.
Every Mall has a clothing store or boutique, and the Mega-Mile Mall is no exception. Here, the clothes-shopping member of the family can do their thing, while the spouse or kids watch tube.
While most Malls don't have grocery stores, I figured why not? So in the opposite corner to the restaurant there is this mini mart where Sims can go to pick up groceries before they head home.
Here is the Mall's bookstore. There are cozy areas to sit and read so you can decide which book you want to buy or you can roam the stacks to your delight.
I call this the Family Fun Center. It's a place where people can come to play games and have fun--as a family or as a way to meet new people.
For the kids, there's a gaming store with pinball machines to play there as well as games to buy to play at home on their computers. It's the "in" social hangout for the older children & teens when they get dragged along to the mall by Mom or Dad.
For the fit-minded, there is a gym where you can work out. There are showers & tubs available to clean up after your workout.
Out in the middle of the mall, there is this pool. You can see the doors into some of the shops from here. I put in stairs going to the roof and put in some rooftop hot tubs but, for some reason, no one will go up there. Not sure what's up with that.
