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: This place was voted the best Vietnamese restaurant in Las Vegas.  I do not agree.  Food is decent, but not nearly the best.\n\nBest thing about this place is that they are open 24 hours!  That's awesome!  We made it here at about 10pm on a weekday.  It is not a little place, but we still had to wait about 20 minutes before we could be seated.\n\nOnly 1 person in our party of 8 was happy with their order.  Those are not good odds.  Maybe we expected too much because they were voted best in Las Vegas.  Maybe the rest of us ordered the worst things on the menu?  It is a very large menu with so many choices.  My wife ordered Pho and was disappointed.  I ordered a Roasted Chicken with rice dish, and the chicken tasted bland.\n\nWell, 7 out of 8 of us will not return here anytime soon.  There are much better options in Las Vegas.
Solution:
2 stars
