What are the apartments in that private area in Chicago called?|128448

Now I can_t seem to locate this area on a map, but I_ve gotten stuck there before and its hard to find your way out. The entire area in downtown Chicago is full of fancy apartments with doormen and such and is elevated to where if you walk around that area you come to a bunch of terraces overlooking Chicago. There are stairs that bring you down to parking areas and such and I remember a grand staircase like park area somewhere nearby. Can anyone find this area on a map?

Look just east of Michigan Ave and west of Lakeshore Dr., north of the Chicago River. Also, it can be just about anywhere just west of Lakeshore Dr. north of where I mentioned above.

Maybe you_re thinking of the area along E. Randolph.
