Problem: I stayed at the Hilton Chicago for my cousins wedding. The service was impeccable. Not only was the staff attentive, they were respectful and careful not to interrupt the guests or make themselves known when serving dinner. I had the chicken wellington and it was to die for! The chicken was perfect and moist but the pastry crust was flaky and crispy. They even had Pakistani dinner options for some of the guests. The amenities were great, and after an open bar the night before, the Mimosas and brunch buffet couldn't have been better! I would love to have my wedding there.
Solution: positive
Explanation: Review writer likes the hotel. There are strong positive words like 'impeccable' and 'great'. Therefore it is classified as a positive review.

Problem: We stayed at the Millennium Knickerbocker last week and it was really wonderful. First off, the staff is excellent. All of our needs were addressed quickly and with a smile. The hotel really was the perfect launching pad for us to take in everything that Chicago has to offer. All of the shopping of Michigan Avenue was just steps from our room. We decided to go for the Shedd Aquarium package. We started the day with a really wonderful breakfast at the hotel and then thoroughly enjoyed our "all access pass" to the aquarium (very cool!). After our long days of sightseeing (and a quick stop at the wonderful martini bar), it was so nice to come back to the room which was elegant, but a very comfortable sanctuary from the busy city. To top it all off, they have the most incredible shower that I've ever used (and, even better, it's all "green"). What more can I say? The Millennium Knickerbocker was a huge part of what made our vacation so wonderful and memorable. I highly recommend it!
