Very impressive.  Yes, Las Vegas has many great restaurants, but what I find frustrating is that many are situated off casinos, and are dark, windowless spaces.  Bouchon is a gorgeous space with wood paneling and floor to ceiling windows overlooking a lovely pool/garden area.  \nThe food was exceptional and I have had many mussel dishes, but this was one of the best.  We all commented on the unique dish it was served in.  Everyone at the table was very happy with their meals.  A great night!
