Old Field Club has that rustic, yet classy feel. Also Check out the Frank Brush Barn in Smithtown
I second Old Field Club however I do not think it holds very many. You should definitely check out the barn at Old BethPage Village Restoration ... it is owned by Dover Group (they are also the owner of my venue) so I am sure they are reasonably priced. They have done a total revamping of their company and hold Bridal Shows with all of their preferred vendors at their various venues regularly.
I'm going to second Riviera. I had my heart set on having my wedding at Hallockville but bringing everything in was just too expensive. Riviera very willing to negotiate. We got a lot thrown in by paying all the deposits up front. We're getting married this October on a Saturday afternoon for I think it was $74 before taxes/fees. Check their Facebook page because they just had a deal up for all remaining 2016 dates!
How reasonable, price wise, is the Riviera? I am interested in the venue for my 2016/2017 wedding.
