On our last visit to Las Vegas we decide to try Rollin Smoke BBQ.  We arrived at around 6PM and they were already out of brisket.  It is what I use as a benchmark for BBQ so I can only provide feedback based on what we had.  We opted for the Baby back ribs and the beef ribs.  Overall the food was great.  I would certainly recommend the beef ribs.  They were fantastic and meaty.  The service was prompt.  This is a dive so don't expect a fabulous setting, but we knew that going in.  The staff were very friendly and the place was packed.
