Is this an elevator to subway?

MTA map shows a subway entrance here... where is it?

Apparantly this is where Sesame Street is. Who knew?

(Perhaps some local mapper could figure out which part West 63rd Street has a new/additional name? Big bird? Bert perhaps?)

this is very confusing, see the raw map data.
to the west are two overlapping buildings sharing nodes, with different addresses.
the building here does not render.
2412/2514 does not seem logical.
as i don't know what data is correct, i'll quietly go cause mischief somewhere else.
thanks.

Can't tell from aerial if this is painted on mini roundabout, or actually a really small full roundabout. Since mini_roundabout is an exceptionally rare circumstance in this US, I'm thinking this roundabout needs to be mapped with a circular road.
