bungalows are very common in chicago's outer neighborhoods and inner ring suburbs. they are almost always brick (both red and blond being very common) and they typically have some degree of prairie/craftsman detailing/ornamentation except for the postwar bungalows which have a cleaner and more modern/less ornamented aesthetic. and the roof ridge is almost always prependicular to the street, ending in either a gable or a hip with an attic window dormer.
one advantage chicago bungalow hoods have over those in some other cities is that chicago is a heavily "alleyed" city. just about every block in this city is bisected by an alley, so vehicles are kept in alley-accessed garages and that results in the absense of sideyard driveways, which i think helps give chicago bungalow hoods a slightly more intimate/urban feeling despite being comprised of detached single family homes.
here are some fairly typical examples of the chicago bungalow:
