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: Arrived around 2:00 PM for a late lunch on a weekday. The place was not very busy. The service was not bad. I think the prices for lunch specials are not too bad (price includes a soft drink), but for regular menu I thought the prices seem quite high. I ordered a chicken burrito lunch special and was not impressed. The only thing that had any flavor on the plate was the rice. The beans were extremely bland, the shredded chicken in the burrito was plentiful but it was very dry, tough and flavorless. I almost had to ask for a knife to saw my way through it. No moisture at all. The sauce they used on the burrito tasted like watered down tomato soup. I had to douse the whole meal with the salsa - and the roasted style salsa is not my favorite. I thought the bean dip that came with the chips and salsa was fairly good. Well, it was healthier than many Mexican meals (according the the menu - no lard is ever used), but it seems at the expense of flavor.
