Meet me at the bicycle parking on 11th Avenue just west of the Gagosian museum on the cross street. It's on the northwest corner of that intersection.  You'll need to go west from the street you are on until it ends and then go south to the next block and go west one more block and you'll be on 11th Avenue then.  After that go 6 blocks south and you'll be there.  You'll pass a bicycle rental 3 blocks before you get there.
