One example is below.
Q: 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!
A: 2 stars
Rationale: The writer has been annoyed in this place and has enjoyed the food. So, "2 stars" sounds reasonable for it.
Q: We decided to try Pin Kaow Thai since we heard good things about this restaurant. It was even voted as one of the best Thai restaurants in Las Vegas in 2012.

However, it was nothing special. I was kinda disappointed, I was expecting more. It's just an average, at most, Thai restaurant. The chicken yellow curry was average, padthai was average, catfish was on the chewy side. The servings were small also for the price. I did like the appetizers (fish cake, and chicken angel wings).
A:
3 stars
