Was 330 N Wabash used as the exterior of Wayne Enterprises in "The Dark Knight"?

I'm on vacation in Chicago right now and have read that both Daley Plaza and 330 N Wabash (old IBM Building) were used as filming locations. My memory isn't so great and since both buildings look somewhat alike, I can't tell which one served as the exterior of Wayne Enterprises. Any Chicago TDK fans who can... show more I'm on vacation in Chicago right now and have read that both Daley Plaza and 330 N Wabash (old IBM Building) were used as filming locations.

Any Chicago TDK fans who can enlighten me?

Thanks! :-)
