I'm looking for some ideas of where to take my new mother-in-law for Christmas Eve lunch in the Bridgewater/Somerville area. (I got married on 12/6!). She hates "upscale" places and is very non-adventurous insofar as cuisine is concerned (i.e., she likes basic American fare), so places like Shumi, Origin, etc. are out of the question.
We've taken her to McCormick and Schmicks the past few years which she seems to enjoy, but I would like something different this year. Any suggestions?
