I lived on 21st and kater for about four years up until a few months ago and I was actually surprised about how many center city places wouldn't deliver to me. This was especialy frustrating becuase I lived at 27th and south for a few months and had no problems. The worst was lombardi's. They had a poor guy ride a bike all the way to 27th and south from 18th and walnut, but wouldn't let him go to 21st and kater becuase it was past south.
