You can still have last minute casino/gambling/drinking time before you leave! Or right when you arrive. Isn't that already unique in itself?
Food wise, not too much to choose from, but you get that in many airports. It does have more variety than others, since it's a pretty big airport, at least! I also like how you can take a shuttle to your hotel (so take that vs a taxi if you're only with one other person/yourself), and the fact that it's only about 3 miles away from the strip.
