Finding food of your taste in Kathmandu will not be a problem. If you stay in Thamel then you will probably feel that you are in some busy downtown streets of your city in your country. Nepali food however is completely different and in all the places in Nepal except for Thamel, Kathmandu, Lakeside in Pokhara, Chitwan National Park you will probably have to eat Nepali food. Which is called Daal Bhaat in Nepali. Daal Bhaat is boiled rice, lentil soup and some vegetable curry dish. In fact Daal Bhaat is eaten by most Nepalese twice a day and are available in any restaurants around the country. Many travellers find it tasty and healthy food however there are large number of them who may not like the way rice is eaten. Foods like chips, sandwich, burger, cakes are not available in rural Nepal due to lack of proper refrigeration systems and ideas of cooking styles. However travellers may find light foods like noodles, biscuits, chawmins etc more amenable than Daal Bhaat.

An issue concerning your health is the purity of drinking water. It is not recommended to drink water straight from tap anywhere in Nepal. Please make sure you have the water boiled properly or purify it with tablets that can either bought in Nepal or be brought by yourself. Bottled mineral water is completely safe for drinking and please make sure seal has not been broken before purchasing.

Please avoid eating food with large meat contents for first few days of your visit and stick with plain and light foods like sandwiches, fruits, salads, bakeries etc.

Soft drinks and beer are available at some places on the trail. Please don't drink alcohol during the day and be aware that alcohol limits your ability to acclimatize to altitude during your ascent. If you wish to drink tea at a tea house, your exposure to harmful bacteria may be reduced if you use your own cup, however, do not follow this procedure to the point of insult.
