Basically these are "private" little areas where people can sit and have lunch on the water, watching boats go by and so on. There is a lantern up top that lights them up at night, and the art on the panels will glow. I like everything but the art they chose. I have never really been a fan of contrived photoshop/3D compositions like this. I'm sure it has some sort of meaning, but there is no plaque nearby explaining what.
