You are given a review about a place. You need to provide a rating from "1 star" to "5 stars" for this place.
One 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!
Solution is here: 2 stars
Explanation: The writer has been annoyed in this place and has enjoyed the food. So, "2 stars" sounds reasonable for it.

Now, solve this: Serenade is a new cafe in the southwest that has already become known for its pistachio latte (it is tasty), and is one of the few coffee shops open late in this part of town (original hours were 8:00am - 2:00am, but I overheard an employee saying that they may adjust their closing time to 12:00am).

Their menu has the typical spread of cafe beverages, from coffee to lattes to frappuccinos. They also serve food, but it consists of dessert type foods: honey toast, waffles, pastries, cakes, etc. Not exactly the kind of cafe you would start your day at by getting coffee and breakfast (unless you enjoy sugary breakfasts). I've only had the drinks here, and I feel they tend to be on the expensive side. Coffee is $3.00 and other specialty drinks are $4.00-$5.00.

Overall Serenade is a nice cafe that offers a charming setting to sit and relax, so I have no problem coming here on a fairly regular basis for a warm drink.
Solution:
3 stars
