MooLattes are from Dairy Queen. Have you had one? Neither had I until this evening.
It's frozen-ice-creamy-coffee type stuff. I had the Mocha one. Your other choice is either French vanilla or cappuccino.
I recommend the small ones though. The large is just way too much, I couldn't finish it.
I do think they could have come up with a better name for it than MooLatte however. Making cow sounds at the drive-thru or saying a word that sounds a lot like 'mulatto' just isn't my thang.
