Been here 4 times in 3 trips to Vegas since October 2012.  Bacchanal is a 4 on some nights but a 5 on its best nights.  The spread is amazing and the food presentation and atmosphere is sophisticated and modern.  Yes, the line can be horrendous just like every other top buffet.  Twice we waited an hour.  Another time we paid an extra $15 per person to skip the 90 minute line.  The last time, we arrived at 5:45pm on a Friday and there was absolutely no line at all, amazingly.   The food is quite good to excellent but has been inconsistent.  3 out of the 4 nights, the King Crab Legs, while meaty and plentiful were way too salty.   As King Crab is the main attraction for many people, I wish that it wasn't so salty, bordering on unpleasantly salty.   Another night, several items at the meat carving station were dry.  Love the shrimp cocktail, cheese station, sliders, and tonkatsu ramen with extra pork though.  And Bacchanal has the #1 dessert station hands down.
