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: So I went to this place and I did like the vibe. Nice open space with tall windows. I got a sandwich and a beer. Food was pretty good. We sat at the bar and the bar tender was attentive and friendly(to be fair, the place was almost empty). My problem is this. My date orders a blueberry vodka and lemonade, but the bartender suggest a different drink which was blueberry vodka, lemonade, sour and some other liquor. Get the bill, $14 for this magical concoction. Are you freaking kidding me?! It's 5pm and we're the only people there and you suggest a different drink and charge me $14. Where the hell are we NYC?! What a joke. Dude, total Dbag move. Worst part is, I tipped him well because he was a nice guy, but in retrospect, I got bent over. Oh well, enjoy it cause im not coming back!
