Pros
The ethics of the company are great. They care greatly about the sources of their ingredients, as well as the quality of food. Definitely the cleanest restaurant I have ever worked at ( I have also filled in at 3 additional locations aside from the Marlborough one, so I can vouch for them as well). The culture is very laid-back and liberal, which is a great fit for like-minded people, but may be awkward if you are not. As long as the company is growing, there are excellent opportunities for advancement from workers who are consistent, who "fit in" with the culture, and who express desire to make a career out of it.
Cons
The sales have been increasing rapidly for quite some time, so doing much of the preparation by hand using "traditional culinary methods" becomes tiresome and difficult if left to the same position every day. Front of house is much easier than back of house as far as workload goes, but it involves customer service, which some may not prefer. Also, the culture tends to favor "cool" people, who tend to get promoted if they are extroverted and likeable, regardless of qualifications. Although most of the managers are very easygoing and approachable, some may not perform their jobs very well, and may result in you having stressful shifts when they are in charge. There seems to be a high turnover rate amoingst less well-established restaurants with managers who end up going to college (after they graduate), and from other managers at said locations who are just incompetent that either quit or get fired. Also, there is a pay cut when promoted from Service Manager to Apprentice (it goes from hourly to salary, but the hours stay the same and the pay averages out to less - but even so, after a relatively short period as Apprentice, you are very likely to get promoted to Restaurant Manager, which is better in terms of pay, work, and benefits. After GM, the opportunities are excellent if promoted - including bonuses and opportunities with corporate (if you are interested in that).
