Your fisheye lens doesn't normally do this (introduce waving curvature into the verticals) which makes me wonder whether this building is not long for this world! Or maybe it's just suffering from the shock of having to shoot a place where so many of its relatives were sent off to the dinner plate. Coincidentally I just had fish for dinner only a few minutes before typing this but not, I think, from here. It looks like it might have been a decent place in its time. It's such a waste to see all of these places winding down.
