Question: is there a post office in grand central station

Answer: No, Although the terminal has been officially called ``Grand Central Terminal'' since the present structure opened, it has ``always been more colloquially and affectionately known as Grand Central Station'', a name of one of the earlier railroad stations on the same site. ``Grand Central Station'' is the name of the nearby U.S. Post Office station at 450 Lexington Avenue, but may also refer to the Grand Central--42nd Street subway station that is located next to the terminal. The name was also used for the renovated Grand Central Depot, from 1900 until its demolition in 1903.
