You didn’t mention how many people you’re inviting, because if you’re doing something smaller, Tarrytown House is very pretty. Probably can do up to about 200-250, which is too small a venue for most of us these days.
Which brings to mind the demise of the Washington Hotel, which was a wonderful place in every way – the caterers were delightful to deal with, food was excellent, decor was well maintained. But I heard that when they had the opportunity to expand to accommodate the larger simchas we all seem to make these days, they opted out. I think there’s a nursing home or senior residence on the property now.
