Given the task definition, example input & output, solve the new input case.
You are given a review about a place. You need to provide a rating from "1 star" to "5 stars" for this place.
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!
Output: 2 stars
The writer has been annoyed in this place and has enjoyed the food. So, "2 stars" sounds reasonable for it.

New input case for you: This is an excellent mexican restaurant! It's clean and has a great ambiance. The food is excellent and the service superb. The only thing I didn't like was their thin house soup but the other people in our party liked it so it was probably just me. We signed up for their e-mail list and they have done a good job keeping in touch with us. Letting us know about entertainers that will be there and special brunches etc. Definitely worth trying!
Output:
4 stars
