Here are my personal recommendations for local businesses in the ReCALC area - Cambridge, Arlingon, Lexington, Concord and REgional. Hence, "Local" - this probably won't mean much to you if you don't live inside of 128.
A note on my 1-star scale: Entries with a star are rated highly: a place I really like, and definitely recommend. No stars means it's a good place, and you should think about checking it out. No entry here means either I've never been there, or I don't like it. I typically don't like posting negative reviews.
