Ugh! If you are referring to those restaurants beside the JMT building, I'd rather they stay just the way they are (plus I lilke going there). I'm not really keen on having a tall building there as it will diminish the presence of the existing buildings.
Plus a retail anchor means traffic galore on an already heavy traffic area. Its also madness given that part of Ortigas is over-retailed already with SM Megamall, the Podium (which is expanding), and so on.
