Don't order the Mucho Gordo Burrito. While the description sounded delish, the execution is awful. The contents are diced into such tiny, tiny bits that it is a mush without distinct flavors. There were also way too many onions; it was overpowering! I had but a few bites, and then pushed it aside. I told the waitress there wasn't anything wrong with it but rather it just wasn't to my liking. We opted to take it home [the literal doggie bag; our skinny Marissa needs all the extra food we can get into her], and in the car for a short period I thought we'd have to roll the windows down.
On second thought, it was so bad I can't imagine it was intended to be that way! I should have sent it back.
I usually find The Sassy Onion to be top notch. Can't win 'em all, I guess.
