La Cuarta - Closed for good?

Living around the 25th street area, "nice" restaurants are hard to come by. LaCuarta was one of the few bright spots. They had a really nice ambience, decent food and pleasant surroundings. I notice the restaurant has been closed for quite some time now and at first I was hoping the owners were on some sort of vacation but it seems the place won't be coming back. A true shame! I was wondering if anyone knows for sure whether they will be reopening at any point in the future or if we'll have to search for classy fare somewhere else. I see a "building for sale sign" on the place so perhaps they lost their lease (?)
