The world’s most romantic city, Paris, has been named the most expensive city in the world to order a Club Sandwich, according to research released today by Hotels.com.

The classic chicken, bacon, egg, lettuce and mayo sandwich, commonly available in hotels the world over, has been used as a measure of affordability by the hotel experts. The Club Sandwich Index (CSI) will give holiday-makers an indication of the costs associated with their holiday destination, using one of the most common items on any hotel menu around the world as a barometer.

The CSI average price has been calculated by taking the real prices paid by guests for a Club Sandwich in 30 global cities. In total, Hotels.com surveyed the Club Sandwich prices in a total of 750 hotels across the five, four and three star category across 26 countries.

In the French capital, the CSI showed prices ranged from an extraordinary $53 for a ‘Club’ in a five-star hotel to a more reasonable $22 in a two-star establishment with the average cost of a ‘Club’ in Paris coming in at $32. The second most expensive city was found to be the Swiss city Geneva, where the sandwich costs an average of $32, followed closely by $30 for a ‘Club’ in Oslo, Norway.

Sydney, Australia, took eighth position with an average ‘Club’ coming in at over $19.
