the big corporations operating in Greece almost forget the existance of this "mall" as a ...mall. Mostly because of its past, (as "few stores next to a supermarket") and also because of its low traffic and low awarness to the consumers of Athens.
If you take out H&M, the "mall" will close in few months. With Golden Hall right next door in a couple of months, and The Mall very close by, there is no future for small chopping centers like that.
The previous smaller version (before the expansion) was a commercial disaster. The few stores were closing one after the other, or simply the big coorporations were moving out and smaller unknown stores took some spots.
Architecturaly interesting this expansion, but size not enough unfortunatelly. The Mall on the other side, is an ugly, dated, messy building, but it was saved because of its size and promotion.
