You can say what you want, I was there, It was mixed Shmogasbard. It was that large building near the road that is blocked to the main part of New Square. (Sorry I dont know the name of the building. I am not so familiar with New Square), But it was the main building and it was very nice.
. Like I said I left after the Chuppah as I had to get back to the City area so I dont know what the meal and dancing looked like. They couple were definatly Chassidic though. (If it was a big room with a Mechiza , or seperate floors)
