A friend will be in town next week, seeking a great lunch before he heads off to an evening of meetings. He's been to No. 9 Park. I'm coming from Cambridge on the Red Line.
It can be chow or high-end. So Red Bones in Davis Sq., for instance, is an option. As is dim sum.
Butcher Shop and the fanastic Duck Confit Salad would be a great choice, but it's a bit of a haul for me to get to and back midweek.
