Some other suggestions to throw out there for consideration:
I am always up for Greek town restaurants to share plates.
Blackbird have a heck of a $22 lunch deal.
Park Grill in the Millenium Park.

Or a picnic in Millenium Park - bring your own brown bag (radical, I know) from any of the following:
- CND Gyros (as mentioned by B above and suggested for April loop lunch before I inadvertently pre-empted it)
-
Pastoral (call in your order for pick up or we can place a group order) or;
-
Farmstand- Oasis (as suggested above)
- Others?

, I wonder if any of the restaurants on the
Riverwalk will be opened by 5/27:
•Chicago River Dog between Clark and LaSalle.
•Cyrano's Cafe and Wine Bar on the Riverwalk at Columbus
•Friendship on the River between State and Dearborn
•Lagniappe Cajun Creole Joynt between Dearborn and Clark
•O'Briens Riverwalk Cafe at Wabash
•Riverwalk Grill between LaSalle and Wells
If the Riverwalk is open, everyone has a choice of the above vendors, and I have been wanting to try Lagniappe for a while now. However, weather is always a factor with outdoor dining, unless folks are flexible enough for a plan B.
Too crazy? Stop smoking my recyclables?
