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
Even though I was only in town for my sister's wedding, and despite being exhausted after spending the whole day doing wedding related stuff, I could not get myself to call it a night early when I'm in Vegas. So when they all came up with the idea to hit up a lounge, I could not pass it up.

Don't get me wrong, I can't help but notice the eye candy that hits up the clubs in Vegas, but being so tired, I just wanted to relax and have a drink. Even though it was difficult finding tables to get our group all together (we had maybe 12 people I think), it was nice to lounge around and have a few drinks. On top of that, everyone in the place seemed to generally just be out to have a good time with no intentions to ruin anyone else's.

It would have been better if the DJ mixed things a little better. But the shadow dancers, they add to the ambiance. You can't not look at them. Some of the guys though should at least try to look at the women that are not just silhouettes too. In the end though, it was a nice night to end the weekend of my sister's wedding.
Answer:
4 stars
