The most expensive club sandwiches in the world

That’s according to Hotels.com which released its second annual Club Sandwich Index (CSI), a barometer that ranks the most expensive cities around the globe based on the price of a room-service club sandwich -- the most common hotel menu staple around the world.

According to their number crunching, the average club -- a double-decker of bacon, chicken, lettuce, tomato and mayo -- from a three to five-star hotel in Geneva clocks in at about $30.45 USD (€23).

The index averages the price of a sandwich across 30 hotels in each city. Overall, 840 hotel menus across the globe were canvassed.

Results of this second annual survey also reveal that on the whole, prices seem to be falling. While the most expensive sandwiches hail from Geneva at $30.45 this year, that price tag is lower than last year's Paris average of $33.10, deemed the most expensive for 2012.

This year, the average double-decker at a Paris hotel clocked in at $27.45.

According to the sandwich index, if you're looking for a more affordable vacation, however, consider New Delhi, where the same sandwich at a starred hotel will cost $9.11.

Meanwhile, the CSI comes the same week as a TripAdvisor index which named Oslo, Norway the most expensive travel destination in the world based on the cost of a one-night’s hotel stay, cocktails, dinner and taxi rides for two people.

Oslo clocked in at No. 3 on the club sandwich index.
