I always get Animal Style (you know, every time I'm in LA or have a car in Vegas), and I'm not a mustard fan. I never noticed it having mustard. I just thought it was all the veggies diced up.
i spent about an hour in the can not long after eating an animal style 3x3 with animal fries. delicious, but probably the least healthy complete meal i've ever eaten.
im going to la next week, so this is good to know. i only knew about the animal style fries and wasnt that impressed with them. ill give it another shot along with an animal style burger with extra cheese.
