Most stores open at 11. Sorry that I didn't see this earlier. Hope you have a great day!

I did not use a master card so I don't know. They probably do but I'd want to make sure as well before travelling that long distance with a pre-paid Master Card and find out that I couldn't. The Calgary Downtown Association page (it features Stephens Walk along with other attractions) has a contact email for general inquiries. You could send them your question in an email just to make sure.

Yeah, there is abundant parking downtown, very close to Stephen Ave. esp. on weekends; even affordable parking on weekdays with the economic downturn. Pretty much everything you need to know is found if you google search "downtown Calgary getting around". Stephen Ave also runs parallel to the C-Train, one block north - very accessible by train or car. The link above includes helpful parking links. My personal fav. is "Eighth Avenue Place Parking" where you can park on weekends and evenings for $2. Great deal. Clean, new, secure, visible and accessible. Google that one too!

Right in the area are some of the best food trucks in North America - legendary stuff. Search for YYC food trucks. I would also recommend a few spots right on Stephen Ave.: Saltlik is one of the best, reasonably priced Steakhouses. The Keg downtown location is also great, a couple blocks away. Cactus Club Cafe is a local chain, really solid, just a touch upscale, trendy. The same is true of Redwater Grille, Milestones and Earl's -- all favourites here in Alberta. At Stephen Ave, you're only 9 blocks away from the Red Mile, the 17th Ave food district. My wife's fav. is Corbeaux - I love it too. French. Authentic bakery (patisserie) and lovely french cafe. We lived in Europe for 4 years - it makes us homesick. Again, as reasonable as Calgary gets. It's an overpriced city, so be prepared for a 20% hike on food prices. If you want some good deals head to Saskatoon, Saskatchewan (it's a thing, for real) or Hamilton, Ontario. Enjoy your visit!! Welcome to Cow Town!!
