The problem with this restaurant is that it is too well known, has too many tables (it is very, very cramped), takes too many bookings and has a poor ipod based ordering "system". In a town where there are so many non-French, it would also help if more of the staff understood English - other than the one who actually is.
Our first visit went quite well and we only had to wait 15 minutes for a table and 20 minutes to get our first course. Our second booking was also made by our hotel, for four people at 7.30pm. The restaurant wrote it down for two people, so when we got there they told us to come back in half an hour. We did and they told us to come back in another 15 minutes, when they told us that our table would be ready when the people on it had finished their coffee, but they couldn't say when that would be. At that point we ''grabbed'' the ear of the waitress from London who had been monitoring our predicament from the background. To be fair she was brilliant and got us a table inside three minutes at about 8.30pm. We ordered and our kids food arrived after about 20 minutes. Ours didn't and they'd nearly finished by the time we managed to get the attention of the English waitress. She discovered that somehow (fat finger syndrome) a comma had been entered on our order and that means that "the adults want their food after the kids had eaten". No-one does that. We nearly exploded, but she made sure that our food arrived as soon as it could, so a meal that should have been finished by 9.00pm latest, ended up not starting till that time and not finishing until after 10pm. Not funny, especially after a hard day's skiing. Added to that your clothes come out stinking of all the food and need either washing or hanging out overnight. At least it's less expensive than some others in Chamonix and the food is tasty.
