Anecdata: I have a friend who is from Detroit. A techie, lived in the East coast and works for a company on the west coast. Visits Detroit to see family.

He says that the Detroit "rejuvenation" is a complete scam. That all the articles in the press reference the same three or four restaurants. That, yes, there is a nice area in Detroit around what he calls "the green zone" (not sure if that is the accepted term or just a reference to the protected area in Iraq) but once you leave that square mile it is a wasteland.

Again, I have never been. But my friend gets annoyed at all the "Detroit is the next big thing" talk for these reasons.

There's definitely more restaurants opening up than just the original few and many of them are opening up outside of the downtown core near other blighted areas. There is a positive, optimistic energy and that sometimes comes across as being a little less critical than they should be of new restaurants. For example, they opened up a ramen/noodle joint and the ramen is just terrible but if you read the reviews from locals, you would think that someone took a noodle joint out of Tokyo and plopped it down in the middle of Corktown. The Vietnamese and Middle Eastern food is good though on account of large local communities of those folks.
