Theresa,
I assume you are baiting us, when your imagination is stilted at KFC and lunchmeat sandwiches....however, if I am wrong, please hand over the keys to your website immediately, selling advertising would simply be larceny.
Anywhoo...I am not sure if we did this before, but, of course, you can use the search function and type in Ravinia. FYI, there is also a Millenium Park Picinic request thread.
When you say downtown, do you mean the City or the loop. I know quite a few folks take the train up to Ravinia. However, my ideal might be to take the train from the Lawrence stop...about equal distance from Lincoln Square and Andersonville and not too far from Argyle.
I am not sure why, but when I think of Ravinia, I always picture Mediteranian foods. Maybe some cheese from the Cheese Stands Alone in LS, and then a bottle of wine and Med-foods from Middle East Bakery...olives, eggplant, pitas, hummous.
Thems my thoughts.
Unchain your lunch money!
