You are given a review about a place. You need to provide a rating from "1 star" to "5 stars" for this place.

Let me give you an 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!
The answer to this example can be: 2 stars
Here is why: The writer has been annoyed in this place and has enjoyed the food. So, "2 stars" sounds reasonable for it.

OK. solve this:
I come to Pittsburgh on business pretty frequently, and a co-worker and I were bored after a long day of trainings and reports. So, we asked the driver for the shuttle at the Westin for recommendations and he brought us to Kaya.

I was not dissapointed. Jamaican Jerk Chicken Wings are amazing. If I retire to a carribean Island and Jamaica has sports books that serve wings like this, it's a done deal. After that recommendation, I turned over my life to the waitress, who was hardly stunning but could've convinced me to propose based on her food recommendations. She guided us through a meal of Jerk wings, Tempura Avocado, some Tacos Al Pastor that we split and a couple different brews that are not sold on the west coast but were very good.

I'd definitely go back, especially since this is the only entry that comes up for Carribean food in Pitt on Yelp.
Answer:
4 stars
