Just for kicks, here is something I put together in looking into ethnic eating options along the 7 line in Queens. It's an uncritical list of ALL restaurants (as defined by SIC Code) within a half-mile of a 7-line Metro stop based on my estimates of platform locations. As such, there are some obvious inaccuracies due to coding inconsistencies. My guestimate of physical location of Metro station platform centers is also a bit sloppy, but take it as it is.
The first page presents the list by restaurant name, while the second page is sorted by stop.
