Help: Potato Leek soup tonight??

so, very long story....but I need some help finding a restaurant tonight serving potato leek soup. Preferably not as an amuse or appetizer, but almost a dinner portion.

Closer to river north the better....

nicer the better....

ideas?

Perhaps you could call around to the various bistros and French restaurants such as Cyrano's, Bistrot 110, Brasserie Jo, La Sardine, etc. and ask what the soup du jour is? I don't know of any that has potato leek soup on its regular menu, and I usually make it myself rather than order it in a restaurant. Good luck!
