I finally had a chance to try it. Well, the burritos are big and when they say steak (or chicken) burrito, they mean it - lots and lots of steak and little cheap filler. However, they weren't all that tastey and I've had much better before. Lots of meat is good, but there needs to be a balance with the other ingredients, which they don't have. If I want a steak, I'll go to a steakhouse. I found the burritos dry and badly in need of more sauce or something, especially at the ends because the ingredients aren't evenly distributed.
It was fine, but once was enough. I certainly wouldn't recommend going out of your way, unless you are one of these people who only care about quantity, not taste.
