There is something about DQ blizzards. Big fan of DQ soft-serve and the blizzard is a quick, portable ice cream fix for us addicts. My fave flavor is the Banana Split and Strawberry cheesquakes-- er.... not mixed together. Their cakes are a family favorite too.
Good summer time tradition and several locations [NE MPLS & Robbinsdale to name a couple] even still sport the old fashion walk-up style.
Granted, they tend to be pricey, you can get sundaes for $1 at any fast food joint now too, but for a treat it's worth it!
