If you like the Subway drawings, you should read some Subway writing as well. Todd posted some excellent observations from the 9 train and others of course. Enjoy your meal.
For those who are out of town, or maybe just live on the east side: the 9 train is like the 1, 2 and 3 trains (it has a red circle around the white number and runs under Broadway and 7th Avenue), but it is a local train (to the Staten Island ferry Terminal, so it never reaches Brooklyn) and runs only during rushhour, thus it is always packed. (Now everyone knows...)
