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
The Better Half turned the big Four-O recently, so I dropped by this joint to pick up some fun party decorations to make her feel really special....ha! After browsing through the aisles of stuff....and there's a lot of stuff here, I settled on a giant "4-0" set of ballons.
