This is a note on finding food along the trekking trails of Nepal. You will find the trekking trails dotted with little lodges and home-restaurants. Do not expect fine-dining or health-cuisine along these treks. You can expect to find local watery noodles (try Wai-Wai - they are great), boiled eggs, hot 'chai' and, of course, ... Coke.
Fruits are also available and are a good nourishment, especially when you trek all day. Typically, these trail-side restaurants also offer accomodation. So, usually, there is no fear of being stranded mid-way on a trek if dusk falls. However, it is a good idea to pace your trek to hit the next major village before nightfall.
Food is brought to these home-kitchen on donkey backs or (at higher altitude where donkeys can't walk on narrow trails) on the backs of the local Sherpas.
Be generous to the locals, always leave a little something extra.
