The Greektown area is nicer. Fairly good restaurants aimed at younger people, I've frequented that area often without a problem.
The "Down Town" area is perfectly fine. I have friends who live down town. Just when you leave that bubble protected by freeways it gets very bad very fast.
Sorry, I was kind of including the Greektown area in that general area. I don't really gamble so I usually don't go their but the food is pretty good. Most of the stops on the people mover seem to be decent neighborhoods as well.
