Un café si'l vous plait

I haven't really noticed how the cost of coffee varies from city to city inside the US...But I sure have made a short n sweet study in Paris in my short while here. Maybe its coz one tends to drink soo many coffees or probably one drinks soo many coffees because of all those cafés scattered at every street corner. Whatever the reason, the cost of living gradation is pretty obvious from these prices -

Coffee At --------------------------------Price in €
School (suburb) -----------------.----------0.65
Near home (posh suburb) ---------------- 2.00
City outskirts ------------------------------3.50
(2 min from posh suburb)
City - pretty setting ---------------------- 5.00
Champs Elysees --------------------------- 6.00

There you go.
