Example Input: Delicious, delicious, delicious!

We stopped in this afternoon after going to a birthday party a few stores down the street, and were very pleased we did. Given the positive vibes on this site, we figured it was very much time to dive headfirst into this experience...

Owner was on-site today, and despite my feelings about Tamari, this place gave us the exact opposite experience - excellent service, excellent and inspired food, and overall a great quick Sunday family meal.

We really enjoyed watching the guys make dumplings and noodles; the open kitchen concept really highlights the culinary virtuosity these guys bring to this place.

Our selections really were mostly ""dim sum"" type things - pork soup dumplings, shrimp with loofah soup dumplings, pork pot stickers, a pan-fried scallion pancake, and an order of cold sesame noodles - for the 2.5 of us (little one was in-tow today...) I was truly taken aback to see how much food that got us (Yes, Rachel C., you hit the nail on the head - we have lots of delicious leftovers now!). All for around $40!

Great service - our waiter was efficient and friendly, and even brought out utensils and a bowl for our little one, without us having to ask!

Yes, yes, yes... we will be back! (Very soon, I think!) Looking forward to trying other dishes from this rather large and interesting menu!
Example Output: POSITIVE

Example Input: My friend and I were looking for a late dinner delivery and decided on Pita Pit as it was already 9:45pm. I called the number twice and it just rang and rang. Third time someone finally picked up and I could barely hear her because their rap music was playing so loud. I ordered a Philly and a Caesar pita, a side of hummus and pita (enough to feed 2 people), and 2 cokes. The ordering itself took 10 minutes because the women couldn't hear me and didn't understand that I wanted Pita with nothing on it to dip into the sides of hummus!

45 minutes later (My friends home is only 1.3 miles away from Pita Pits location) a guy comes with ""our"" order. I close the door and realize I didn't get any drinks, but by then he'd sped off. I call back and explain that not only did we not get drinks, but upon further inspection we got cookies instead of extra pita!

The guy had a thick mexican accent and didn't seem to understand what I was saying. Again there was music playing so loud in the background that I had to yell so he could hear me. He tells me they didn't charge me for the drinks so basically why should I care (at a total of 16.00 for two sandwiches, they obviously charged me for it). I tell him that I'd like the pita and drinks and he then mumbles ""shit"" while trying to find my order. he says there's no drinks on the order (I have a copy of the order that has my drinks and pita scribbled at the botom) but he can see if they can get the driver to come back.

He says he can't and that's when I go crazy. I work as a food delivery service dispatcher, so I know that its almost mandatory to send a driver back if they have forgotten something. I tell him this and he says ""no"". I then tell him when they DO bring my order that I want my money back for the horrible F*cking service. This man then tells me to watch my mouth and to ""not talk shit"" to him. I repeat that I will be getting my money back and if they don't come in a timely fashion that I'll drive down there and make a formal complaint.

20 minutes later: no drinks, no pita. I call back and get a girl again. I explain who talked to me last and she goes ""that little f*cker I know who that was"". I'm again asked if I want them to bring our drinks (YES) and she puts the delivery man on. He explains that no one told him to make his way back down and that he will and it will be THIRTY MINUTES. I tell him we'll just come down cause that's too long to wait. He then tells me it'll be more like 10 and asks if I'm sure I want him to come by with just drinks (..YES).

15 minutes later (midnight on the dot) I get my drinks and pita (1 pita..to share between 2 people) and he looked totally uninterested in apologizing for the 2 HOURS of bull.

The food was good (who knows if they spit in anything because with the way they were acting its quite possible) but that part of the experience was totally trumped by the horrid customer service.
Example Output: NEGATIVE

Example Input: I'm really confused about all the rave reviews for this place. We went last night based on a neighbor's recommendation and the yelp reviews.

We ordered 3 siciliana pizzas, and all three were completely charred black on the bottom. All had a charred chemical taste to the pizza. The pizza oven at the back had smoke coming out of it. I've been to wood oven pizza places before, and never experienced anything like it?

We asked the staff about this, and the teenage ""chef"" at the oven rudely stated that that was how the oven made them and nobody else had ever complained. Whoever owns this restaurant should be ashamed.
