I have loved visiting this place ever since I was a wee child to get the delicious milk shakes (and occasionally a yummy burger too)! They have 30 flavours and you can mix up to 3 flavours in your milkshake. On my most recent visit I had licorice marshmallow as my flavour while another in my vehicle had chocolate mango grape. On previous trips here I have enjoyed butterscotch as my flavour. It is often lined up with foot traffic and the drive-thru itself is really impressively busy. Interestingly enough I noticed that Peters' Drive-In is opening new locations elsewhere now too! But this location has been a fixture of Calgary since 1962, and deservedly so! It's hard to find a good milkshake on occasion and this place certainly delivers!
