I've been wanting to go to RUB in NYC and haven't made it yet so we thought we'd try the Vegas version while staying at the Rio.
I had the nachos w/ pulled pork for my "entree" and they were good but certainly not the best pulled pork that I've had. Extremely salty, I felt like I needed a gallon of water when I got done.
I'd still like to try the one in NYC to see if it's any different and will probably get the burnt ends just because they sound interesting.
RUB at the Rio is a worthwhile stop if you are already at the Rio but I wouldn't make a special trip to go there.
