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
Yeah, Yelp led me a little wrong here, as did the menu. Was looking for a hungover guilty gorging of dogs and tots, ended up feeling worse than when I went in.

The owner is a nice guy, who is trying very hard, but they are missing some things. First off, the hotdog quality just isn't good. "Boiled bologna" is how my date described it, and she hit it right on the money. The toppings were pretty good, very sugary and sweet. We had three dogs and tots. The dogs were luke warm, not grilled to order, not even really done. The buns are good, very sweet too.

Here's my thoughts: increase the quality of the dogs and show that off, doesn't have to be organic, but should be a good name. Grill the dogs to order, takes a few more minutes but I'd come back for it. Make sure everything that is supposed to be hot is hot (chili, tots, etc.) and everything cold is cold (slaw). It's that difference in temp that makes a great eating experience.

Yeah, maybe I'm being a picky jerk, but I'd like the place to succeed.
