I had to stop on the way up to Boston and came across a place called Rufus BBQ & Jerk, at 285 Silver Lane, East Hartford, CT. It is right next to a gas station, so it could make a good pit stop.
I only tried the Jerk chicken and fries, and they seemed pretty good. I wouldn't drive 100 miles for Jerk chicken (maybe that's just me), but it certainly was an improvement over most highway (and off-highway) stops. That seems to be damning them with faint praise, but we ended up taking out and eating the chicken along with a bunch of other things later that day, so it didn't have my full focus.
In addition, the people at the restaurant seemed nice, fwiw.
