The problem is not really Paris but the euro which is too strong, I understand that comparing to American prices it's too much ... But if you take a train to Geneva, you'll see prices there are 30% higher than in Paris ...In Geneva, the cheapest at a restaurant is a pizza which costs 25 euros per person and I don't go to touristic places.
In Paris, 33cl Coke at a brasserie cost an average of 5 euros, a cup of coffee about 2,50 euros.
I understand what you say as I experienced the same situation in Geneva a month ago.
@ Reinaldo & Zafir : in Paris, prices are the same at touristic and non touristic places. I live 2' walk from Trocadero and for professional reasons have lunch at different areas of Paris, sometimes popular and not touristic at all and even there, a little bottle of mineral water costs between 4 and 5 euros and a coffee about 2 euros ... If I have the same coffee at the bar, it's cheaper but I won't leave my table just to save 1 euro. Prices are higher or lower depending on the restaurant level and if it's a fashionable place, independently of quality, prices are always high. A Coke cost exactly the same it doesn't matter if it's diet or not ... Coke or Sprite cost the same as mineral water, sparkling or not ... And this is also valid in the outskirts of Paris. Drinks cost expensive in general as they try to earn money on this as restaurants try to have cheaper prices on food to attract clients ... A 3 dishes menu for 15 euros, then you spend 15 euros more in drinks. Even at Mc Donald's, a little bottle of mineral water, 25cl, costs 2 euros ! How much is it in the USA? The difference is due to the high value of the Euro ... and if you go to Switzerland, food cost 30% more expensive than in Paris.
