If you haven't been to Potbelly's, you probably don't live in Chicago and you probably don't like sandwiches. If that's the case, you can probably stop reading this post. Like most "faster" food chains, their process is pretty much perfected and as a result the food is always the same (which in this case is good).
So I'm not writing this to review the food, I'm writing to say that employees at the Potbelly's at 45 E. Roosevelt (essentially at the corner of Roosevelt and Wabash) are always joking around and having fun. I'm not saying this is a problem, but just an observation. To be honest, it's kinda nice, usually you get a stale experience at these types of restaurants. Good to know Potbelly's is a little different.
