Never again.
That place had some of the most disgusting food I've ever had in my life. In addition to rotting vegetables in the salad bar, the soup was alternatively tasteless or extremely overly salty to the point of not being consumable. I have tried 4 different soups there, and each was as gross and disgusting as the next. Yes, it's only 10 lira or so for a mixed soup/salad bar/rice meal, but it is *beyond* nasty. The soup had lumps where they shouldn't be, unidentified chunks of something, uncooked chickpeas in the nohutlu pilav, and undercooked grains in any soups where grains should be. They seriously messed up tomato soup, which is kind of hard to mess up. They totally screwed up the ezo gelin soup, which had rock-hard pieces of bulgar in it. The lentil soup was extremely salty and unpalatable, while the vegetable soup's vegetables were questionable at best.
I give this place a failing grade and rank it almost as gross as Fudu, which actually had really nice little taste packages but had quite bad vegetarian wraps. I think that's unfortunate, but more fair than a soup/salad bar having absolute crap soup and rotting salad.
DO NOT GO TO BY CORBACI SOUP BAR AND SHAME ON YOU ISTANBUL DAILY SECRET FOR SUGGESTING ANY HUMAN BEING WITH TASTE BUDS EVEN THINK OF ATTEMPTING TO ENTER INTO THE DOORS OF THAT SUBPAR ESTABLISHMENT.
