Hands down, one of the best pizza/pasta places in Kensington. Don't be alarmed by the relative shady looking exterior, or the very diner-esque interior. The food here is fantastic. I have enjoyed both the pizza and pasta here and fell in love with their lasagna. It's seriously amongst the best lasagna I've ever had (sorry mom).
Vina has apparently been around for a long time. I discovered it only because a friend who lives and work nearby swears by it. Naturally, when watching a hockey game, he would order from Vina whenever we needed pizza. I started ordering from them whenever I hung out with him. Hurts the wallet, but makes the stomach feel good!
Vina is not expensive though, unless you order from them often (which I had started to do). They also offer discounts when you pay certain ways and if you pick up instead of getting delivery. Cash will obviously get you the biggest discount. I would say I've probably eaten their food about 50 times, and it was always prepared perfectly.
The people who work there are also great. They have always been courteous and they have built quite the clientele of regulars as a result. I've never eaten in, but I've often seen the same people during my regular pick-ups. They also have a good following of Calgary's finest, so if you have any warrants out for your arrest, I would choose another establishment!
