Grand Central Terminal is a hub of activity with people either walking very fast or running. You can quite quickly say the who the tourists are because they are the ones who stand still for more than a minute while they gawk in awe.
The famous 22 story building, resembling a clothes iron, on 5th Avenue, New York, is an impressive structure. The clock is a 19 foot cast iron clock from 1909. Right opposite the building, across 5th Avenue, was the famous sandwich place called Eisenberg’s. I had their fantastic Reuben, which was out of this world!
