I actually worked at that one a bit in college (and the one on Longmire).
I know their main "office is in the one one Longmire. And the one on University/6 gets a TON of traffic. Wonder if it was a rent issue? Or medians/construction- a lot gets blamed on that these days lol.
Could also just be that staffing 3 locations is difficult. Kitchen staff gets there at like 3am, and the college kids who work there get in at like 530 am. I would guess of the 3 locations, that one was the best choice to go. Longmire is their main office, and university/6 likely has much more traffic than that one did.
