Inclusive Restaurant style Wedding - Ceremony+reception (insignia style)?

Hi there! I fell in love with Insignia (from the site at least) but it is all booked up for weekends in 2016. Are there any other restaurants like it in Long Island that could handle a ceremony + reception for <100 people? I'm having trouble finding similar options, though they must exist...I really liked the decor and the video on the site looked so lovely!

Thanks so much!
