A great way to escape the city...Especially amazing in Spring when the cherry blossoms are out. I love the Japanese pond, the famous NYers walk with plates for Arthur Miller or Lee Krasner and of course the green house.
Luhring Augustine did a good job of converting an old warehouse/storage facility into a blue chip commercial art gallery that stages four shows of contemporary art per year. Which means you can catch museum quality shows in an unlikely spot, away from all the Chelsea pomp, and it actually has friendly staff, instead of a cold gallerina sat behind a desk pretending to be on the phone.
