Thanks for your help. Yes, there are numerous mexican restaurants in
the yellow pages for Minneapolis and St. Paul. I've tried a large
variety of them but have not exhausted the list by any means. Also, I
have found that I tend to like taco shops that are not listed in the
yellow pages -- you know the hole-in-the wall style ones with a poor
building but amazing tasting food :P

Someone else mentioned making my own. I made carne asada on several
occasions back in San Diego, but always with the help of my friendly
mexican neighbors Sometime I might attempt to do it myself, but for
now I would prefer to locate a taco shop where I can just purchase the
burrito as fast food. There are an endless list of places here that
sell "carne asada burritos" but I want the burritos that follow the
style that I found is common to the majority of the Taco shops in San
Diego.

Thanks again
