It's not a coffeeshop, it's an ice cream shop. And it has pretty good ice cream too. That platform is a popular spot for wedding photos, but they almost always face the other way. Hardly anyone thinks to photograph the Brooklyn side. Nice shot.
Perhaps the weather kept people away, but it also might have kept the platform free of clutter. I absolutely love the quality of this photo in its detail and tonal quality. If you don't mind, I'm going to take a screen shot.
