Teacher:In this task, you are given Yelp reviews. The task is to classify a review as "POSITIVE" if the overall sentiment of the review is positive or as "NEGATIVE" if the overall sentiment of the review is negative.
Teacher: Now, understand the problem? Solve this instance: First of all, let me start by prefacing that I am an authentic Hong Kong Chinese living in the San Francisco Bay Area where there is a lot of quality Chinese restaurants. So my expectation may be different from a lot of Las Vegas locals.

Average 4 stars? Where did that come from? The food here is mediocre at best - in fact it would be considered bad quality if you are one who's used to San Francisco area restaurants, but I assume there's just not much reasonable Chinese food there in Vegas - though I have to say I am disappointed as there seem to be a lot of Chinese restaurants as I drive around so I would think that there's some competition - it really got me wonder if the other Chinese restaurants are even edible.

For example, the boiled chicken we got was a disaster. I have never seen boiled chicken that stale, and it's obviously microwaved, with a 'pool' of yellowish oily water on the plate. Never, ever, had I seen that in any Chinese restaurant in my life.

Fried string bean - boy, did they use oil from 10 years old to cook it?

Or perhaps we were just unlucky that day.

Service is attentive though - the waitress in there really did try her best.
