Part 2. Example
Although I did enjoy the food here, I was completely unimpressed (and slightly annoyed) by the overpriced margaritas. I ordered a platinum which contained "fresh" juice. It tasted like it had sprite in it, so I thought surely she gave me the wrong one. It turns out that "fresh juice" is really margarita mix on tap from the same gun as the sprite. I asked for something fresh to replace the horrible margarita and received a rocks glass with just muddled lime and a salted rim. I'm not sure it contained any tequila. Horrible! It's not that hard to make a fresh margarita!
Answer: 2 stars
Explanation: The writer has been annoyed in this place and has enjoyed the food. So, "2 stars" sounds reasonable for it.
Part 3. Exercise
cheap hotel rates for sure. but the rooms are just okay. This hotel is considered old and I think they should fix up the hotel rooms a bit. I do like the location of this hotel, even though it's located toward the south side of the strip, they have a monorail that will take you to Aria, City Center and Bellagio. In fact you can just walk to Aria without going outside. No need to worry about scorching hot weather or rainy seasons.

If you want a decent room and good rate, I recommend this hotel. But do not think this is mirage status, it's one step lower. Don't even compare to bellagio or higher.

If you don't care about fancy schmancy rooms, and your idea of a room is just a place to sleep, then Monte Carlo is a good stay. The pools are pretty nice: man made beach and lazy river. You will be close to the more popular clubs: hakkasan, marquee, etc.
Answer:
3 stars
