I was living in zurich last year.. the small apt i was living in - about 45sqm was CHF 800 per, just over US$800, it was very moden, quiet, overlooking a park and with a tree covered mountain behind it.. My 32sqm studio in palermo is US$500, not nearly as nice as the zurich apt, or as quiet or with forest behind or a park infront.. So it works out per sqm about the same.. however i pay alot less than most people here, as i know when i was looking for an apt 6 weeks ago alot of landlords were asking around US$700 to US$800 for a studio..
In gent in belgium, i was paying 600 euros for a 3 bedroom/3 story (one bedroom was big enough for a single bed and not much else, the other 2 around 20sqm) house, and gas, electricity, internet, cable TV etc was usually under 100 euros a month... this is for 2 people... So again cheaper than here...
Food: i cant remember the prices of most stuff, but when i got back to arg i was surprised at the cost here..
Some things i do remember was - in euros:
1lt UHT milk - 0.56
1kg Yoghurt - 1.25
1kg muesli with fruit and nuts - 1.25
Wholemeal bread (1kg i think) fresh - 1.40
Gouda cheese / kg - 6
here is a link to the supermarket just down the road i would buy most stuff at:

All of the stuff above is alot better quality, and tasted alot better than here.. apart from the milk which is just as bad as here...
