Having spent several years in Memphis I have at least a passing idea of what rib place should be. This one stacks up pretty well. While it lacks an obvious smoker outside attended by sweating barbecue experts, it offers dry rub ribs. That suggests that they are willing to let you sample their smoked product before it gets slathered with sauce.
I had a half rack of dry ribs and they were excellent. There was plenty of meat and it was well cooked with lots of juice. My wife had the loaded spud which was a potato with meat and cheese and some other stuff it was really good.
The number of customers both inside and for takeout indicates that the place is well respected. Recommend you give it a try.
