I don't know how true this is so don't hate me if I am wrong. I watched a video of a guy who wanted to escape the everyday stress of modern societies, so he packed his bags and went to Nepal. The guy claimed to have stayed in a hotel-like accommodation with good and healthy food and all that cost him $5 a day. That leaves plenty of money for good wine, Cuban cigars, and other types of pleasures.
If it's that cheap, one might even consider spending a few months on holiday in Nepal to save some money you would otherwise spend in large metropolitan areas.
I don't know if it's talking about Nepal but if you look at some of the articles I've read and compare it to the country I live in Indonesia, it's 1.50 times lower than in the Special Capital Region of Jakarta (the area I live in) but this is only for a place to live. although indeed the area and type of hotel adjust but for food that is in fast food restaurants such as McD, Burgerking etc. I think Indonesia is much cheaper because if you look at several sources, the price of food at food places like the ones I mentioned above in Nepal is around 975 NPR or maybe the equivalent of $7.75 different from in my area which is only $3 or $4 on average.
