Of all the Vegas steakhouses, this is my favorite. You can actually pick between dry-aged and wet-aged and grain fed and grass fed. Their dry-aged steaks are excellent and my friends who like wet-aged say they are very good as well.
An edge that Craftsteak has are its excellent side dishes. The only one who outdoes the Yukon mashed potatoes is Robuchon and not by very much. The only restaurant that has better creamed spinach is the DC Palm which has a different recipe for creamed spinach than all the other Palms in the U.S.
There was one occassion where the service was a bit slow but other than that it has always been an outstanding restaurant. It is expensive but worth it.
