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.

Example Input: Referred by a friends glowing endorsement. I was impressed. Besides the unique atmosphere folks of all types fill the tables, booth and bar, moderate noise levels and a robust menu. It all makes for what appears to be a terrific gem just of old scottdales Fifth Avenue. I sat check it out.
Example Output: POSITIVE

Example Input: I've been going here since I was little on family trips to Vegas. So I know how much it has changed.

This use to be the spot where we'd invite family and friends to eat whenever we're all in town at the same time.

The food here is no longer good. I think due to the 24/7 hours, they've changed the way they make their food and it's no good.

The pho isn't good at all. The soup doesn't have the beef flavor in it at all, it just doesn't taste how pho should taste.

The service here sucks. You're already waiting in a long ass line just to finally get in and wait some more. Once you're seated, the waiter/waitress will just give you your menus and leave...not even dropping off water. Sometimes it'll take almost 30mins until they comeback to take the order.

The last two times I went were not good at all.

I went with my friend and we were seated in a corner and completely forgotten about.

Another time, I went with my parents and sister. My sister ordered the chow fun and the waiter messed up our chow fun order with another. When we told him the order was wrong, he got the chow fun from the other table and gave it to us to eat...the other table had already eaten out of it...

The prices have gotten a lot more expensive as well.
Example Output: NEGATIVE

Example Input: This review is of the service at the bar only. Went in at 8 pm on Thursday 3/20 and sat at the bar. There were a few available seats in the dining area and a table in the bar area. We sat and watched as the bartender chatted with another employee at the other end of the bar and when he was done picked up a cell phone and talked on the phone ignoring the customers. He then waited on a few customers at the other end of the bar still ignoring us. When he finally decided to wait on us, I asked for a glass of water and a menu and my sister asked for the beer list. He gave my sister the beer list and went to the other end of the bar and made a few drinks and chatted with people. Never gave us a menu and never even looked at us again. We thought about going over to the hostess and getting a table but I really wanted to see how long he would ignore us. (He was not busy) We watched as a group of people came in after us and sat at the table in the bar area and were waited on by another server. They had menus and drinks. We finally decided to leave and he probably didn't even notice. Saw a lot of great reviews but I guess we will never know. First and LAST time I will go there. BTW went around the corner to a different restaurant and had great food and service.
Example Output:
NEGATIVE
