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: I was fortunate to be invited/included with a hotel group who were being treated to lunch as part of this restaurant's effort to help stimulate more business in this downturned economy. Part of lunch was the "grand tour" of the facility which is huge, seats 1200 people, employees 200-300 and hopes for business in Las Vegas to start an upward spiral. Even with all comped, i must say the service was efficient and friendly, food items for all 7 of us were tasty, plentiful, cooked well and imaginative. Drinks were good as well. If I had a negative, it was that the noise level is very high. But, what they do is done well. It isn't a quiet sit down type of place... its' bubbly and party time atmosphere.
Output:
3 stars
