The second floor above Brix was formerly the expanded (and at one point very popular) billiards room of the Bricktown Brewery, abandoned when the Brewery sold and adjusted its footprint. I've spent many an evening playing pool and looking out of those windows.

I will say that while numerous undeveloped floors certainly and obviously exist in Bricktown, I believe most people including posters on this board are unaware just how many upper floors ARE occupied by functional (and in some cases high-end and outstanding) office space. I think the perception is that there has been zero upper floor development when in reality there has been a considerable amount.
