This place was a lifesaver; I arrived in Chamonix around lunchtime and was famished. They have a good vegetarian menu but not much for vegans. The server was very accommodating however - a rarity in France - and I had the summer roasted veggies on a baguette with a salad for 6 EUR. It was excellent. I would definitely eat there again but it would be nice if they expanded their vegetarian menu to include more 100% vegan options.
Cons: not much for vegans
