I went to a wedding yesterday
The wedding was at Sunset Harbour in Patchouge. The place is nice, I hear it's inexpensive too. The food was very good.
The DJ was great. I would recommend him to anyone, he had everyone up on the dance floor, he did a lot of fun things, not just music and dancing. It was Deja-Vu.
Those are the only vendors I know of.
Hope it helps someone.
