Horrible Experience with the Hilton Staff
I have to say that I'm disappointed and in awe with the staff of this hotel. As a frequent business traveler that have been to many hotels, and I have never experience a more despicable service than what I have experienced tonight, especially in NYC.
We were entering the hotel at around midnight after picking up some chicken and rice from the Halal guys, and we were screamed at by the security guard to show our room key. In a quick response, we flashed our cards and told him to relax. 
The security guard immediately called the security manager Henry to follow us to the lobby lounge area where we were eating our food. Upon my third bite, the security manager approached us and closed off the lounge area and informed us that we were not allow to eat there. In the most unprofessional manner that I've ever seen in a hotel, he directed us to eat in our room cause we might dirty the area. His tone and the way he treated us as the hotel guest was appalling. The most ridiculous part was that the security manager even tried to confront us when we wanted to file a formal compliant on how rude the security guard was at the entrance of the hotel.
Bottomline is
- Hilton NYC is not a customer first hotel, your complaints will be ignored and brushed under the rug
- Your Hilton Diamond status and loyalty to the Hilton chain doesn't matter, cause you will get treated like crap regardless. 
- The lounge in the lobby is off limit to the hotel guest
- The staffs are rude
- Security guards and manager do more profiling than the airport security
Stay away from this Hilton hotel if you want to be treated with respect, doesn't matter what Hilton Honors status you have. Don't let these people ruin your trip, take your business to the Starwoods or Marriotts where they would actually appreciate your business.
