Roxy Vape is a pretty cool place. Situated within an existing convenience store, for something outside of the downtown core it's pretty convenient to have a place open 'till midnight, 7 days a week.
The shop carries a number of high-end liquids that can't be found in a lot of other shops, and they actively seek new ones. If you're looking for a particular kind, give these guys a shout - you might be surprised. They also have a selection of mid-level juices. While there's no lounge area to sit, all the juices are available to try.
They also have an impressive selection of vape equipment: a number of starter kits for new vapers, impressive selection of regulated mods, various 18650 batteries in stock - all authentic. The only clone selections they carry are of RDAs (which, imo, is fine). The guys are always cool to talk shop, so head over to them if you're looking to ask questions.
