Being that the company I work for is based out of Chicago, I've had Potbellys once in a blue moon while working out of the mothership. It's funny when folks from our Chicago office visit due to our location in Charlotte has a lot of the same chain restaurants that surround our Chicago office.
Either way, I was sad to see my Salsaritas spot go, but having the location in the Overstreet Mall didn't really make sense (two Salsaritas in a two block radius!).
I like what they did with the dining area.... they really took some time out to think about the local art and even have a custom skyline bench that borders one of the walls.
I came on an off peak lunch hour, cause their lunch line is ridiculous (well any place Uptown has a mad lunch rush). So I think the employees were "recovering" from the previous lunch rush. Trash was still on the tables, but I did see someone cleaning up while I was dining in.
Sailed through the line pretty quickly so no complaints and my Mediterranean sandwich was pretty darn good... should have added the chicken.
