Need Two Restaurant Recommendations

I'm in LV for two more nights and need some restaurant recommendations. I've been eating decently so far this trip but haven't gone the moderate to expensive route yet, mostly because this whole trip was put together at the last minute.

So I know there are an incredible number of great restaurants from which to choose, but I'd like to know your top five or top ten (because getting a last-minute reservation could be problematic). I'd prefer to go the steakhouse route one night and just about anything the other. I have no dietary restrictions, thank goodness. Youtube has been helpful but not definitive.

I'm switching hotels today and will be near the south end of the Strip, but I have no problem going elsewhere so long as I make it to the shows for which I have tickets (Fantasy at the Luxor one night, O at Bellagio the other).

Any help will be greatly appreciated!
