Not quite twice as big but yes bigger. Every time I go to the Tulsa store, it's dead. I know plenty of people from OKC that shop there too, once OKC's store opens, no more need to drive to Tulsa WF. I'd see OKC getting a 2nd location before Tulsa due to our population and the pent up demand. Tulsa has better alternatives already.
Thanks for the clarification on size. I would have to disagree with you about how busy that Tulsa store is. I go there at least once a month (sometimes more frequently) and it is always teeming with people. Not sure what time of day you've been there. It's even crazier on weekends.

You may be right about OKC supporting a second location before Tulsa -- and that stands to reason, as we have Norman and Edmond as suburbs, which trump Jenks and Owasso, IMO.

I do agree that Tulsa already has better grocery alternatives than OKC, although the new Crest on the south side is very nice, Forward Foods serves an important niche, and Crescent Market is fairly decent.
