Yes! I miss Sumaq too. That outside terrace was heaven (and the freshly squeezed OJ really made a difference)
the new one opened not long ago. The restaurant/bar isn't new but I believe the smoking area is. I believe it was opened on late 2014. They don't advertise it much though.
I hadn't realized you were a local (yet I keep writing to you in english, being a native spanish speaker too, haha).
Que tengas buen viaje, saludos desde SCL
