in all fairness to the OP, the REAL expat ghettos are really mid-levels and disco bay. in fact these two places are so ridiculously 'expatty' that makes me laugh everytime i go there
have dinner on staunton or elgin street on any day and tell me it's not a ghetto?? of course these are extremes but i still think mid-levels has a huge expat influenced environment
haha.... so basically expats live everywhere! Poor locals, they can't escape us!
