Tamarind Looks to be Closed for Business at 614 S. Wabash

We've received a couple emails stating wondering what the deal was with Tamarind Sushi at 614 S. Wabash.  Judging by this picture as well as the "closed" status on Yelp, it seems like their fate is sealed:

It seems like this retail strip hasn't had much luck for restaurants and businesses.  Tamarind was one of the few that has been there for awhile, but it apparently has couldn't sustain.

Interestingly, the new 16-story rental building "30 East" is progressing quickly and would seemingly be bringing a lot of additional potential customers to this area.  Maybe rent is going up for this space?
