Believe it or not, the southwest side of the city still exists. Check out Archer Heights, West Elsdon, and West Lawn. Head south down Pulaski from the Stevenson down to 71st St. and just about every sign is in Spanish. Also, Clearing, along 63rd from Harlem to Central has a rapidly growing Hispanic population. This area is quiet, safe, has good transportation (The Orange Line tends to be cleaner, safer and more reliable then most other El lines), and is considerably cheaper then a comparable neighborhood on the north side. For most of last year La Ley, (107.9, En Chicago Manda) had wrapped the El cars on the Orange Line with their advertisements. Definitely a considerable Hispanic presence down here.
