I have only eaten at the 9s 5-6 times - they were somewhere within a 30-minute or so drive from Chlemsford-Andover-Lowell, MA area back between mid Oct and Mid Dec, 1985. And, I always got the same thing - the 16-oz prime rib ... after a week of seafood and pizza I needed a big ol' hunk of cow, so that's where the guys at work took me.
I actually enjoyed the food - and was amazed that it was quite a bit cheaper than what it cost back home at a Steak & Ale or The Keg for half as much food. If I ever get back to MA it's on my list of "must eat at" places.
