It's hard to tell by looking at this shake from above but this is the "New! Chocolate Malted Crunch" Shake by Carl's Jr. I still like the strawberry shake better, but I think new flavors are the in thing and my guess is the shake will grow on me.
About a week and a half later (after what I wrote above and delayed posting) ... brings me to right now. There will be another picture in the next post as I just got back from Carl's Jr. where I got that shake again, using the drive-thru, but I wasn't able to see what makes the shake the way it is and the picture won't show much either.
