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
Ok, if you have no other options.

I work graveyard, and this is one of the only places that delivers near me overnight. Their pizza is ok, NY style. But, aside from their pizza, I'd advise to stay away. I don't think there's a single fresh ingredient anywhere to be found. That includes their meat/chicken. It's not too hard to throw a chicken breast on a flat grill, but this place insists on using pre-cooked chicken on it's items.. And you can really tell. All of their appetizers are frozen, and fried.

If this is your last ditch resort, then go ahead.. But if you have other options, exercise them!
