Vegas Prime Rib

I am about to head off to Vegas for an annual trade show and I am interested in finding any hidden away "local secret" places for Prime Rib. I have done Lawry's and it is wonderful...and expensive. I have heard taxi drivers talking about unadvertised Prime Rib specials at places you wouldn't normally think about for Prime. Of course, I have never been able to remember where they were. Now don't get me wrong, I am not looking for cheap low quality hunks of beef, just something that doesn't come with Nurse Rachet spinning a salad at my table.

Any Vegas insiders out there willing to share?
