Pros
This company works hard to create consistency across their many stores. So if you've worked at one, you know how things are supposed to run at any other store. Its easy to jump in from store to store. Food is well made, and on the healthier side of things.
Cons
Can you say Micro manage? I have worked a couple different restaurants as a server. Every server learns tricks to keep up when things get super busy, but First Watch worries more about doing things exactly the same that they often over manage. Too often we aren't allowed to work smarter, but instead work harder, just to follow this model of "everyone does it the same". Depending on the particular manager at that particular store, it can get overly stressful to keep them happy when all you're trying to do is your job well.
