In Kathmandu you can withdraw money everywhere with your bank card (cash machine). You will change money (cash or traveler cheque) easily in the exchange counters everywhere in KTM or Pokhara and also Lukla or Namche (however the rate will be much lower in Namche or Lukla ).
In Kathmandu and Pokhara, the price does not include your lunch and diner (between 5 and 8 euros/day/pers), outside the cities everything is included in the cost of the trip excepted extra expenses like fresh beverage (beer, coke…) and sweet (mars, snicker…)
Try not to change money at the airport where the rate is lower than in Kathmandu.
Keep at least one receipt if you want to convert your roupies when you leave the country.
