First, the Melrose Central Building added their first retail tenant, a Checkers fast food joint (which is actually really good). So that was evidently successful enough that they've decided to expand the retail.
I wouldn't be surprised if the Concourse Plaza food court is struggling now. On the one hand, they have a lot of new clients from the new office building that just went up above it, but, stupidly, that building also cut off pedestrian access from the residential buildings to the west and south. So they have less foot traffic from that market segment now.
