several supermarkets in town for cooking own food (super u probably the cheapest)
best cheap eats are the poco loco, midnight express, and a variety of boulangerie....some tasty high class food for celebrating at the end of the trip too....there are a couple of good savoyarde restaurants and i actually think the indian restaurant (annapurna) is pretty tasty....neither of those options was super cheap though...
there are tons of gear shops....with cham3s being the dominant....of which snell is the most popular, largest, and in my opinion home of the best beta
there are at least 6? guidebooks you could buy....the two volume snow, mixed and ice books, plus the new piola aiguilles rouges and the new piola envers des aiguilles, plus the cragging book, and the 4000m snow climb book.....but the classic rock routes are all best researched in out of print guide books at the ohm....where you can photocopy any book NOT in print for 10cents a page or something like that.....if you can find the old piola guidebooks those are awesome....there is also a vogler classic rock routes book and the british alpine guides....voglers is out of print...but the british alpine guides are available...lindsay griffin i think authors those....also two volumes....if you want all of them bring 300 euro or so for books alone.....i got gifted some old hand me down books from a retired climber a bunch of years back....bit out of date but with the ohm topos gets the job done.....
