Do they have a weekend club? If so how much to come in.?

Sorry, but I've been in the Bronx, & City Island for 55 years. I never heard of such a place. Are you looking for a Bed & Breakfast kind of place?

I do not know. I do know that they have a separate restaurant and a catering Hall. Not sure if they turn the catering Hall into a weekend club if they do not have an event

I don't know about that
