Eating on top of Dallas? Okay, so it isn't on top of Dallas, but it is in the ball that is a famous scene in the Dallas Skyline.
The food is good, not excellent, but the skyline view makes it all worthwhile. It rotates while you eat so you can see in all directions. If you eat early enough, you might see some window washers outside as well. They do offer a Sunday brunch, which provides great food then. I do not recommend really young children, but pre-teen to teenagers would appreciate the atmosphere. Also, if you want to take someone special out on the town, this is definitely different.
On the second floor is a lounge where you can relax if you just want cocktails before you go out on the town. It is right next door to Reunion Arena and pretty close to West End/Deep Ellem if you want some night action.
