7 days left till my office relocates to the RenCen!!! I cannot wait to get out of present digs [[Southfield) and into the new place...

I am looking for recommendations outside of the RenCen options for lunch..I figure that there are plenty of places within walking distance, or people mover stops that I can check out...and I am up for the old school find out yourself method , but I was wondering if there are any awesome lunch spots that any of you recommend?

I am not really interested in the subways or Jimmy Johns of the world as those advertise themselves well enough. I am familiar with the RenCen food court and some of the chain places around it but as for the more hidden treasures I am at a loss.
