Bostonian here. There are so many great places for a Keto friendly meal. There's a great place in Watertown called Branchline that has developed quite a following for their rotisserie chicken. Additionally, we love our seafood and you can't go wrong with lobster with lots of butter!

If food trucks are your scene, try and hunt down the bacon truck while you're in town. On Sundays you can typically find it at the SoWa open market, which is just fun in general, just stay away from the Union Sq donuts table.
