See one example below:
Problem: This is my go to place to get the best chicken Pad Thai! Also the price is super good, considering most places have high prices and poor quality. Love this place, its definitely a top 5 fav for take out.
Solution: POSITIVE
Explanation: The overall sentiment of the review is positive. Hence, the label is 'POSITIVE'.

Problem: I want to be fair. I can see why people give this place a 4-5 stars rating base on its food. Their pho is actually pretty good. No question about it.

The reason that I gave it a one star was entirely for our unpleasant experience over there. This may probably doesn't happen to most people, so just want to state this ahead to keep it in mind.

After we were seated, I asked the waiter if they accepted credit card. I thought it was opened in Chinatown and they printed their menu and signs in Chinese, and most Vietnamese people speak Chinese as well, so it was natural that I asked him in Chinese. He paused for 5 seconds and stared at me awkwardly, and that he said he only speak English. That's fine for me, but the way that he was starring at us for 5 seconds was really awkward and sort of rude manner.

In any case, moving on from this. While we were eating, this same waiter came from behind and told me to move my chair forward so that it gave more spaces in between two rows of the tables. I don't think my chair position was occupying that much space, but in any case I don't mind to move either way. But he never said word like ""sorry"" or ""thank you"", but rather like giving me an order or something.

Had it just end there, I would overlook this and gave a rating of 3 to this place, but what came after was really unpleasant.

After the meal, I went to the counter and paid the bill. The cashier gave me back the changes, and I put the tips at the bill plate on the counter (which seems to be what others were doing too as I observed). After we walked out, that same waiter chased from behind and sort of yelling that we forgot to pay the tips. What? I told him that I had left the tip amount on the counter's plate already. He looked mad like I was lying to him and asked,""Are you sure?"" in a pretty rude manner. He acted in a way that like I stole money from him or something. I explained to him again and he just turned around and walked away. Bet that he was cussing on the way back.

Looking back, I think what might have happened was that people leaving tips at the counter's plate instead on the table like we do in California. This might confuse in some ways that they could mistaken who had paid the tip or not. In any case, regardless what happened, it is very rude and unprofessional to chase after the customer to ask about the tips, and question you like a suspect additionally. I mean, come on, we are talking about few dollars of tips here. This kind of attitude was totally uncalled for.
Solution:
NEGATIVE
