Teacher: You are given a review about a place. You need to provide a rating from "1 star" to "5 stars" for this place.
Teacher: Now, understand the problem? If you are still confused, see the following 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: 2 stars
Reason: The writer has been annoyed in this place and has enjoyed the food. So, "2 stars" sounds reasonable for it.

Now, solve this instance: Las Vegas has become a place for gourmands and foodies in the last ten or fifteen years as there are some very good and very upscale restaurants there. Hamada seems to be part of this upscale tradition taking place. The interior is spacious yet relaxed with low lite mood lighting and a surprisingly well stocked fish tank. The Sushi is very good just about anything you get at Hamada is usually good. I personally would recommend the Beef Negimaki. On a side note it is important to know that Hamada attempts to be as authentic as possible as occasionally the Japanese wait staff seem to have trouble with English, some may find this to be unprofessional I found it oddly endearing.
