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
I've been to this location several times. They grande bowl works well for my resolve to avoid carbs. I always it minus the sour cream, rice or chipotle sauce but its still very good.
What I loved was the fact that on my visit this weekend the person taking my order was super nice. She not only made sure that I got the right order but double checked by letting me know each of the other ingredients in the bowl. She even offered to give me extra veggies since I was not having some of the ingredients.

Oh - and I did not know, they have a catering menu as well!

Its the great service that makes me go back everytime, even though there is another Rubio's close to where I live!
