They aren't cheap, but nothing in Manhattan is and they did a really great job.
A little flakey at times and slow to set up on the day, but all in all, the flowers and other design elements more than made up for any other shortcomings. Absolutely gorgeous.
This is the only vendor we were disapointed with. It's pricey, the photographer was unfriendly, difficult to locate throughout the night and seemed to have no interest in posing people or getting a good shot with the end result being that he in fact, did not get good shots. The pictures were poorly balanced and the lighting was horrific (despite the fact that we had a lighting company and our friends photos are lit beautifully).
