This Qdoba is in the heart of the University of Pittsburgh and seems to follow the typical college semester schedule. It stays open fulltime from roughly August to April and is closed during the summer break. It has amazing food and typically has a shorter line than Chipotle, which is about a block away.
They had a student who decided to show off on the roof for some girl a few years back. He jumped from one roof to a lower roof and managed to get wedged between the 2 roofs. Qdoba was forced to close for remodeling after their upstairs dining area wall had to be demolished to get the student out of the gap between the buildings.
Long story short, the whole restaurant was remodeled a few years back and looks great.
