Sushi Loca in North Las Vegas
Old school vegas style, go to Hugo's

More mainstream:
Del Frisco's (yes, it s chain, but my favorite by far, and my favorite location after the NYC flagship -- my squadron has a locker in the cigar humidor there)
Red Square in Mandalay -- its not just for cocktails, food is excellent
Bouchon -- I think the one in Vegas is Thomas Keller's best location (over Napa and BH)
and don't forget for your quick meals:
Burger Bar in Mandalay is awesome:
