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
Coming here on Christmas eve was such a bad idea :(

Service was not good. The place was not packed at all and we waited for a very long time to be greeted. And when we did get greeted it was from someone either than our server. We ordered the cheese fondue and it was so gritty. I saw the sign outside for the steak and lobster special for $19.99 so 3 out of 4 people at our table ordered it and I wish I asked how many ounces the steak was. It was literally the size of my fork. I was still hungry after my meal.

Won't be coming back.
Answer:
3 stars
