There was a survey that claimed OKC was a Top Five retail market, that's all I'll say.
Also there HAS been interest from Whole Foods and similliar retailers in OKC (which the powers that be would want them in downtown). Whole Foods is an upscale organic grocery "experience" (quite tasty I might add) that doesn't draw from the local grocery shoppers, but those looking for the "experience". It wouldn't need 6,000 in downtown to support it. It would need people in a metro that like that sort of thing. We have Alexa, and that's a start.

Downtown still may need a very small grocery store for your staples once this is all said and done, but I wouldn't exactly call a Wal-Mart Neighborhood Market a small grocery store. I hope Wal-Mart doesn't try to enter this market before anyone else to stall the entry of more retailers.
It's like the chicken or the egg. Downtown needs a grocery store for more growth, b/c living downtown w/o can get annoying. You have to drive and fight traffic on 23rd.
That's all I got...
