Well, IIRC, Damen and Central both run north-south. Do they have an address? The thing to remember about Chicago is that there are good areas, and bad neighborhoods interspersed together. You can be fine, but 3 blocks away is an area you wouldn't want to be in in broad daylight.
I went to school at 115th and Crawford, a fine area, but within one mile was Robbins, a quite rough area. Cabrini Green, one of the worst, most dangerous housing projects in the city, was walking distance from the Loop (ask me how I know!- BTW, not anywhere near Central.)
Give me an address, or at least a block number, and maybe I can be of more help.
