Peter's Drive-In is one of the best places in Calgary to get a milkshake. There is so many flavors to choose from, I personally have to decide well ahead before I order.
We went here last Saturday evening around 9 pm and the place was still packed! Drive-through took about 30 minutes waiting. It was worth if for the milkshake though. There is only one size but for a little over $5, it is a huge cup.
