Here in Boston, WFNX does the Leftover Lunch, basically covering from the 70s to the 90s. Kind of true to how WFNX has been sounding lately, there really is no incredible depth to the playlist, but host Julie Kramer will pull out the occasional nugget.
In Providence, WBRU has the 95-Minute Retro Lunch, which airs at noon on weekdays, then they have a "brunch" show on Saturday mornings. A little more depth that WFNX, but basically covers the same time frame, 70s to 90s.
