sazdbaz, American express used to issue those travel cheques.. they stopped that in Nepal.. I am glad.. not a big fan of travel cheque.. just higer charges for those...
These days they have this Nabil Debit card where they load most of your money in that 2K, which you can use here to make purchase, but if you use withdraw cash at ATM, there is some fee.. not sure about it.. so it's really hard to bring actual cash these days..
