Paris puts the bite on visitors
Paris has the most expensive club sandwiches in the world.
The Economist magazine has the Big Mac index, which has become a credible economic indicator, but serious travellers are more likely to order room service than nip out to the nearest Maccas for a snack.
So, an online travel service has come up with a comparison for more well-heeled travellers, using one of the more popular and ubiquitous items on the menu - the club sandwich.
And Paris is the most expensive in the world, according to the global survey by Hotels.com.
They price-checked club sandwiches at more than 750 hotels in 26 cities in Asia, Europe, North America and South America to help travellers size up the affordability of different national capitals.
The result? Paris topped the list with an average price of $US33.10 ($A33.06) for the iconic chicken, bacon, egg, lettuce and mayonnaise sandwich that's a fixture on virtually every hotel restaurant and room-service menu.
Geneva placed second at $US32.56, followed by Oslo at $US30.50. New Delhi was cheapest at $US9.57. Berlin and Brasilia were bang in the middle at $US17.77 each - slightly more expensive than New York's $US16.93.
Tokyo came in at $US27.65, Hong Kong at $US18.35, London at $US18.71 and Toronto at $US16.05.
"Paris may well be the gastronomic capital of the world, but travellers may be better off sticking to a croque-monsieur," Hotels.com spokeswoman Alison Couper said.
For the record, a Big Mac will set you back around $5 in Paris.
