The Plaza would benefit from a small convenience store/bodega--or several. The problem is where to put it/them, because it determines who it would be convenient to. It would probably have to be on a parcel that is not controlled by the owners of the Country Club Plaza buildings.
The other issue -- in regards to serving hotel guests -- is that Plaza hotels aren't congregated near each other. There are three nodes: East Plaza Marriott and Courtyard by Marriott; West Plaza near the intersection of W. 47th Street and Madison; and South Plaza at Wornall. Hotel guests and apartment residents probably aren't going to walk 8 blocks to a convenience store. Apartment residents will just get in a car and drive.
Ideally, there would be small convenience stores spread around the Plaza area: in the base of the V-shaped new development at 47th and Madison; one located where Cafe Trio is; and another wrapped around the base of the Alameda Tower parking garage; near St. Luke's at 43rd and Washington--where that church is.
I still question if there would be enough pedestrian traffic. A lot of the recent development isn't dense enough to support these small markets.
The other issue is that many in the immediate area would probably oppose convenience stores, and many immediately assume it would bring in a bad element at night.
With the changing retail landscape, the Plaza might have to open up to the idea of one of these types of operations. Spaces might not be able to stay leased all the time, and at such high rents. The owners might have to consider alternatives.
When I lived in NYC, there was a deli in the base of my 36-story apartment building that stayed open all-night. It had the deli-counter but also hot food trays, and salad bar. I went there almost every day, and got a good number of my meals there.
If I could redevelop an area much more densely than has been happening in that area, it would be these parcels:

I'd put up at minimum 12-to- 20-story apartment towers on all those surface lots.
I'd do the same here:
