I tell everyone that you can get any kind of food in NYC and that it is often better than you will find anywhere else. The exception is BBQ. It's not that we don't love it and it's not that we don't have people who know how to cook it. There are clean air rules (so I am told) that limit the cooking method to something less than the ideal / real southern BBQ way. (If you know the regulation, post it here please.)
Having pontificated, let me say, this place serves decent ribs. Their sauce is pretty good too and they are not stingy when they apply it.
If you are an experienced BBQ hound, then you probably will not be awed by Tennessee Mountain. I thought it was OK until I did a back roads tour in Florida and found a guy making BBQ out of a trailer down the road from a 4X4 bog. Yee Haaa! The smell was so good, we drove over a median and right into his back yard. It put every other offering to shame.
Blue Smoke is better and there are other places as yet unexplored (by me, anyway).
