I've been to Hello Bistro a few times, the 1st location I visited was in Oakland. Simple, clean food, with a build your own variety.
I can't say the same for this location in downtown Pittsburgh. Yes, the food and the concept was the same. But this place was a mess even the employees looked sloppy and handled the orders like a public school lunch lady. And nobody wore a belt or maybe it was "show your plumber's crack while you make a salad" day.
Trash was overflowing and debris were all over the floor from the ordering line to the exit. Even worse, the employees clearly saw this and just didn't care.
Bistro is that last thing I would think of after visiting this location.
