Please be sure that trekking generally takes you to remote regions of Himalayas. Lodges are basic and provides few foods items. You will get a simple menu everyday that will offer some western and lots of Nepali meals. The meals are generally freshly prepared once you order. Most of the lodges will have noodles, soups, rice items, curry items, hand made breads, basic pizza, spaghetti, macaroni, egg items etc. In popular routes some lodges also offer chicken items but generally meats are not fresh so it's suggested to avoid it.
