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: This has got to be like, the cheapest buffet in Vegas! That being said, I had low expectations going in so my review is not quite as disgruntled as the others.

Came for lunch with the free voucher you get as a hotel guest. Standard buffet options including Mexican, Italian, Asian, Salad and Desserts. Nothing was terribly tasty but I've definitely had worse (for more money). I enjoyed my salad, enchilada, deep fried ravioli (best idea ever, btw) and mini cheesecake.

Fish didn't look amazing so I stayed away (a rule I hold true to when dealing with suspect seafood) and service wasn't amazing (took forever to get a drink refill) but otherwise, I think this is an ok place if you're in the area and need a cheap meal.
