The most expensive cities for a round of drinks revealed

If you're off on holiday to Paris this summer, then brace yourself for bad news at the bar: it has been named as the most expensive city in the world for a round of drinks. In the city of romance, a round including a beer, a coffee, a Coke and a glass of water will set you back an eye-watering £13.68.

The study, by ethical coffee supplier Honest Coffee, looked at the cost for Brits to buy a round - after exchanging their dwindling pounds - in 30 cities around the world.

The most expensive

Paris £13.68
Dubai £12.87
New York £11.98
Hong Kong £11.59
Chicago £10.96
Singapore £10.90
Sydney £10.88
Los Angeles £10.45
Auckland £10.43
Melbourne £10.30
London £9.90

If you were with a group drinking beers, meanwhile, then by far the priciest place to drink is Dubai, where a beer costs an incredible £8.78. That's followed by Hong Kong at £6.31, Paris at £6.14, New York at £6.09, and Singapore at £6.02.

Australia is home to some surprisingly expensive cities in the study. It has always been notable for costing the earth to get there, and is now clearly somewhere that will fleece you for every last penny when you arrive too.

Movements in the exchange rate have had a pronounced impact on the cost of shopping in the US too. Where once it was considered a shopping destination, now the fact that a beer in Chicago will set you back £5.22 or a cup of coffee in LA £3.06, goes to show that you'll have to keep track of your cash if you're travelling to the US.

Londoners may be keen to discover were the survey was done, because they seem to have got some deals in the city - including a beer for £4.99, coffee for £2.71, Coke for £1.22 and water for 98p. The whole round came to £9.90 - and not many Londoners regularly get change out of £10 for a round.

The cheapest

At the other end of the spectrum, Cairo emerged as the cheapest place for the round - at just £3.92.

The cheapest
Cairo £3.92
Cape Town £4.75
Lima £5.30
Mumbai £5.34
New Delhi £5.40
Bangkok £5.52
Rio de Janeiro £6.47
Mexico City £6.51
Istanbul £6.73
Santiago £6.75

The dominance of Africa, South America and India on this list, may offer food for thought for travellers this summer. Certainly the cost of getting to these destinations is fairly astronomical, but the prices when you arrive could make the trip less expensive overall than somewhere closer to home with sky-high prices.

Of course, what's not shown by studies like this is something we know from cities we are more familiar with: that wandering slightly off the beaten track pays dividends. In London, for example, you can leave the swanky bar of a posh hotel, walk for less than five minutes to a Sam Smith's pub, and get a round for almost half the price.

Wherever you go, therefore, if you check travel blogs for advice, and talk to locals, you can track down far lower prices a stone's throw from the overpriced cafes and bars in the tourist traps.
