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
So there is an argument about this particular establishment at my job.

One Camp states if you need to be um more....regular....go here.
The other camp loves this place.

I watched this argument for about a year before I decided to try Riva's.
I was glad I did. The portions are very large and tasty.

I had the chorizo breakfast burrito with cheese and potatoes. I was extremely pleased to see that the burrito didn't eat its way out of the paper bag via grease.

I have joined the love it camp here at work and for a quick bite I think you will too!
Answer:
4 stars
