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
My aunt raved about this family that used to cook amazing Mexican food out of their house years ago. After she heard that they opened a restaurant, we decided to go one night. The food was decent but the service was almost nonexistant. After being there for about an hour I managed to get 1 refill of my drink.

The fajitas were good but they only gave 2 small tortillas. I ended up eating most of it with just a fork. Didn't feel very fajita-ish to me.

The salsa was good but my family complained that even the mild was pretty hot. I like heat so I enjoyed it.

2 stars
