Looking for restaurants/bar/places in Montreal where they sell different types of bottled water (fancy or not). Any ideas?
You might be able to find different brands at "gourmet" shops; try "Van Houte/Gourmet Laurier" on Laurier St. (outremont side), 5 saisons (both locations, outremont & westmount) might have a few good ones; There's a new "fancy" gourmet store on Victoria that might a some.
Another place that surprised me with a "good" selection of bottled water is the pharmacy on the corner of Avenue du Parc & St-Joseph (the south-west corner)
As for restaurant, I don't really have a clue, I don't usually buy bottled water, but if memory serves me well, you could find better selection at higher-end BYOB restaurants.
as for bars, most serve simple Perrier/Evian small bottles or plain naya kind of water.
Check out Milano's in Little Italy. They have a slough of bottled water (both flat and sparkling) at the cashes ... mostly Italian brands ... I hear Fiuggi is really good.
