We got our months wrong. Chicago Chef Week is actually March 17th through March 22nd. Good news is that you can still plan ahead. Enjoy.
Acadia (1639 S. Wabash) and Gioco (1312 S. Wabash) are offering $44 three course tasting menus. Click here for link.
If those two restaurants don't do it for you, there are some other solid options albeit not in the Sloop.
