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
Winding down from a very busy weekend in Las Vegas and tired of buffets. We yelped Ribs and this mom and pop showed up. It was just what we were looking for. Bountiful home cooked ribs!

We were a party of 9, mostly hungry cheerleaders. We ordered the Family meal of Rib Tips, Baby back ribs and BBQ chicken with all the sides! It was tender and delicious! We also ordered a side of Beef ribs, they were the best I've ever had! Tender and not too fatty!

We'll be back next time were in vegas! A party of 6 cheerleaders, a 13 year old boy and two adults ate for under $90! Wow, good food, excellent friendly service, I'll be back.

Try the Arnold Palmer and the Dirty Water (like an Arnold Palmer, but sweetened)
Answer:
5 stars
