I ate an unhealthy percentage of my meals there in law school, it was about the only place that fit my budget at the time. I believe I could get 4 tacos for $.89 back in the day. Once I started getting a paycheck, I never went back and probably never will. Bu it served me well as a starving student.
Panera make me angry. I avoid it at all costs. When I used to travel to Atlanta alot, there was a Panera across the street from the office. I'd take an early morning flight, and when I was a couple of stops away on the MARTA I'd order breakfast on the app to pick up on the walk to the office. It was never once ready and correct when I picked it up. And we're talking about a bagel sandwich and an apple.
