It is such a shame that a place that has such an amazing view, falls flat in every other category. So during the summer the rooftop terrasse on top of the hotel de la montagne is one of the veryyyy few roof tops in Montreal. There is a 'pool' if you could call it that. Personally, I wouldn't want to step in that at all. You can find women (I think they are strippers from Wanda's next door) sun tanning during the day by the pool.
Usually you go for drinks with a group of people. The service is terrible. It is slow and unfriendly. The drinks are ok but your standard fare. The decor is outdated. The food is decent, but it doesn't make up for the service.
Go for the view, stay for one drink and leave.
