According to the new Zagat guide, the average price of a nice dinner out in London will run you far more than one in any other large city around the world. The average three course meal and a glass of wine costs £39.09, or about USD$79.38. Comparatively, it's $71.82 in Paris, $71.28 in Tokyo, $39.19 in New York City, and $31.74 in Los Angeles.

Not surprisingly, Londoners eat out less than those in other more sensibly priced cities. Londoners eat out just 2.5 times per week, compared to 2.9 in Paris, 3.6 in New York, and every other day in Tokyo.

One of the reason's for London's particularly expensive restaurants is that they simply use better ingredients, many of which are now sustainbly-raised and organic, and consequently more expensive. More than half of those surveyed by Zagat (59%) would pay more for sustainably-raised food, and 54% said they would pay more for organic food.

"Today's diners have a better understanding of what their food choices mean - not only to their health, but their impact on the environment," said Tim Zagat.
