Came here twice with my boyfriend during our recent trip to Montreal and fell in love. The tea selection is fantastic, the staff is very friendly, and there are some very affordable tea sets here (I walked out with two different sets to add to my collection, as well as some more tea). They do a really nice Chinese tea service, explain everything to you, and don't rush you out the door. In fact, the first time we went, we only stayed an hour and the staff joked about how quickly we were leaving. The shop is extremely elegant and relaxing.
I didn't get a chance to try the food, but they also serve a selection of vegetarian snacks.
