I've never been to Chicago (connecting thru O'Hare doesn't count, does it?) but I've got a client who needs Chicago-themed food at a reception (I work for a catering company in San Francisco). The only things I can think of are deep-dish pizza and special hot dogs we once had to fly in for another client a long time ago. Can anyone suggest what foods are special to the Chicago area? I should add the client is requesting 4 pieces of food per person for this reception, and is on a tight budget. Many thanks for any and all suggestions!
