Well, the windows would ruin the forced scale of the top facades, which are supposed to be larger buildings in the "distance", and seeing our normal human heads out the windows would be weird.
But still odd that there aren't windows...it better not be screens...biggest pity is the view would've been GORGEOUS. Is it possible they'll cut out the windows later?
Or could it be that the kitchen is gonna be on the top level completely, and bottom level is all the seating? Nah, that'd be weird.
