Hi,
I know these three places do whole pig:

Beach Park, IL 60099

Sun Wah BBQ (Chinese)
1134 W. Argyle

Close to the Argyle Red Line stop.
T&C Meat Market (Greek-Puerto Rican)

(T&C also does whole lamb)
You could also consult this thread on

Do report back on what you did and how it came out.
Regards,
