While eating lunch we noticed a long line of ants along the wall at our booth. We of course got up and moved all our stuff and alerted an employee. The issue is that after being notified nothing was done. Patrons continued to sit at the booth with the ants and we'd have to tell them not to sit there. This continued to happen so I told another employee about the ants hoping someone would actually come out and remove them but it still was not addressed. The ants were still there on the wall when we left = FAIL. If this was acceptable in the front dining area then it makes me wonder what is acceptable in the kitchen where I can't see? This will be my last visit to this Panera Bread :-(
