Manhattan Mall(100W.33rd); Apple Store(401W.14th)

it means that Manhattan Mall is at building number 100 on West 33rd street, and
the Apple Store is at building number 401 on West 14th street.

it would help if you could get the nearest avenue that crosses these locations...

Justin Xu asked this same question, i'll go see if his post has the cross street.

This is what Justin posted as the text:

""Manhattan Mall(100 W. 33rd): Use the mall to cut through between Penn Station and the 34th Street subway station when it's raining."

If one knows what cross streets frame Pennsylvania Station, you could pin it down to within a couple of blocks. Of course, i doubt if either one of these members will be in New York looking for the Apple Store at any time in the forseeable future.

ok, for the record --
penn station is between 7th and 8th avenues...
