Fine mall. It has some pricey botique and furniture stores, nail salon, a weird yoga/bike place, cheap shoe store, jewelry store. Nearby outside the mall are a few restaurants, like City Bites that moved outside the mall. The mall is not very crowded at all usually. There's a Santa every winter, that's crowded. The rest of the time it's quite sparse in shoppers which I like. There's also the "dollar" theater (it's $2 now, but $1 on Tuesday nights). I like the theater. It's older, sure, but less crowded. The commenter below makes me laugh... "risking your life over?" Please. Northpark Mall is statistically very safe, and so is the area. A few property crimes and car break-ins every now and then happen everywhere. That's hardly "risking your life." The person should have called the non-emergency police number after a break-in, not mall security. After car break-ins, about all you can do is report it to police and call your insurance company.
It's the only mall to visit in OKC if you're not a rampant kid. Quail Springs is too obsenely crazy and Penn has better stuff. And it's on Northwest Expressway. Check out Classen Grille on one end, for breakfast. A ways down NW Expressway (on the way to Super Target) is Texture Salon - get your hair cut/colored by Anastasia there. Come back through and stop across from the hospital for lunch at the diner (really!). Spend the rest of the day shopping and then see a movie.
This mall is not quite where it should be, but it has come along way and has a lot to offer. The carousel in the middle of the mall is very nice (and affordable)
