Mustang sally's Montana

We went to eat at mustang sally's Montana this weekend for my grand kids birthday's. what a big disappointment. We ate one of the big hulk burgers and the kids had there meal. When we ask for a box to put our left over food in opening the box it had +/- 20 ****roaches in the box. The manager of this branch did not even came to us to say sorry for what happened, she is such a rude person .
