Vantaggi
Fantastic people/culture with a good balance between work and personal time. There is also a vibrant social life in the office which is greatly facilitated by the lack of snooty and otherwise holier-than-thou attorneys which can be fairly commonplace in large corporate firms. The Real Estate practice is very highly regarded and the firm is expanding at an extraordinary pace.
Svantaggi
It's Boston so the compensation levels are not the same as New York and the extent to which you're likely to pick up huge multinational clients with complex legal needs, while possible, is substantially decreased. This is offset, however, by smaller startups from the BioTech and Life Science mecca of Cambridge if you are interested in that area of law.
