Just got back from a delightful, though too short, trip to Paris. Didn't drink any Coke, though I saw it in restaurants and elsewhere priced well below $4. (We drank mostly mineral water.)
I can imagine a French visitor to any US city (not just very expensive ones such as NYC) looking at the cost of a glass of house wine at any US restaurant ($4 up) and thinking "The complete city is one big tourist trap." That opinion and the one at the top of this thread would be equally unfair.
When my travel companion and I discuss our next trip, one of us always says "yes, but it's not Paris," and the other nods. We'll probably go somewhere else next time - Africa was this morning's topic - but it's not Paris.
