Food is entirely up to you and how much you eat,it's cheap low down max £4/day it gets more expensive the higher you go, but if you stick to dahl bat you can eat all you like high up for 450/500 their currency 2/300 for breakfast, stay off the booze if you are on a budget wait till you get back to civilisation
