I have a friend who works in Westford, and I work in Stow (route 117). We'd like to meet up for lunch now and then, but have a hard time figuring out where to eat. Last time we met at Bamboo in Westford. It took about 25 minutes for me to get there, which is not ideal. I would love recommendations for places somewhere in between, and preferably right off of 495. Any ideas?
