In some cities, even a "cheap date" can burn a hole in your pocket.
According to Deutsche Bank's Cheap Date Index – which measures the cost of a movie-and burger date in 32 global cities in U.S. dollar terms – London is by far the most expensive place for a simple night on the town, while Mumbai is the cheapest.
The index measures the cost of cab rides, McDonald's burgers, soft drinks, two movie tickets, and a couple of beers.
In London, this basket of items would cost $121, compared with just $23 in Mumbai.
U.S. cities don't even break the top 10. The closest is New York, which comes in at No. 11 at $93, just under Auckland's $96.
