I'll chime in with a dining recommendation - I took the significant other to LV about 1.5 years ago and we had a great dinner at Hugo's Cellar - this is off the strip in downtown LV in the Four Queens Hotel/Casino.
Being off the strip it is probably off most people's radar, but I found the food and atmosphere just as good as any of the restaurants on the strip, and if I remember correctly it was decently priced.
