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
Looking through places that I checked in and wondering if I should review. Stumbled on this one, funny because I was probably stumbling while I checked in! I'm so glad I did because DAMN.

This place was amazing! Open late, quick, cheap, and effing heaven. I mean, it's late night tacos and stuff, but everything tasted so fresh, and was pretty much cooked right in front of you.

I fell in love with DJ's and I will definitely stumble my way over here at the end of the night next time I'm in Vegas.
