Hell no. I won't eat at any place that doesn't have a food inspection sign with a passing grade in the window. I live in California, and there are people everywhere now, selling tamales and some popcorn crap out of carts or just the trunk of their car in the parking lot of Walmart. I used to tell them they needed to stop before they gave someone food poisoning or worse, but they don't seem too bright. Now I just ignore them.
I used to go drinking with some buddies back in my carousing days and they would always stop at these fucking burrito trucks at 2AM after the bars closed. I ate a few, but my stomach didn't like them the next day, lol. I wouldn't touch that crap now.
