I'm going to preface this by urging you to not go out and eat both of these ice cream creations in one day. You'll have many regrets, and you may feel a little sick. All that aside, I took one for the team.
I started with the Dairy Queen Blizzard, which Jeremy is a fan of. My DQ was all out of Guardians of the Galaxy Vol 2 cups, so it is possible this item is super popular. I found the vanilla soft serve was too sweet for me, but I was a fan of the cookie/brownie pieces mixed in. Visually it looks kind of bland and not terribly appealing. I paid a little over $3 for one, so it certainly won't break the bank. There was also little in the way of advertising for this ice cream, even though the movie just came out.
Right across the street from my DQ is a Cold Stone Creamery. I talked about their new Wonder Woman ice cream the other day, so why not follow up with a taste? I'm not a fan of dark chocolate, but I went in with an open mind, and was pleasantly surprised! The dark chocolate berry mix was actually delicious. The chocolate shavings and added raspberries were great. The gold shavings were a nice visual touch. You'll pay a little more (around $5) for this, but it's worth it. There were posters and banners for the ice cream all over the store, which was awesome to see. Shame my DQ couldn't show the same enthusiasm for GotGV2!
The winner in my opinion is Cold Stone. I'd absolutely buy it again!
