The address on Fiona's magazine is 4503 Wolfcrest. 1) There is no Wolfcrest St. in Chicago. 2) The zip code on the magazine (60640) is real but is on the north side of the city, not the south side. The address is supposed to be south, based on when Fiona was discussing rent costs and everyone told her, "South Side rent in a place like that shouldn't be more than $600."
