America pt. 2 (wouldn't fit as a comment)
I've said this before, and I'll say it again: the burrito is one of the main reasons I moved to San Francisco. Ridiculous? Perhaps, but the burritos here come straight from Jah's... taqueria. That's right, taqueria. That's what the place is called when it is truly what a burrito is meant to be. Crews, I know you can back me up on this, because they have good burritos in Texas as well.
Rumor has it burritos were invented in the Mission District, which I live on the edge of and eat multiple times a week at the four-years-running voted best of the bay burrito joint. In fact, it was just a few nights ago that a very well-traveled man named Ben Gibbard told me that the best reason to come to San Francisco is for the burritos at Taqueria Cancun. He also stated that they were the best ones in the world. They have three locations, but the absolute greatest one is a mere two minute's walk from my apartment. I have eaten one at 3am after a night of drinking only to wake up the next day and eat one for lunch/breakfast. The egg and chorizo ones are good when I find myself in that situation.
If I want something a little grimier, or if I'm at a bar more into the heart of the Mission, I can also go to El Farolito. It is almost as good as Cancun, but it will wreak havoc on your body. Before I moved to SF, I thought of El Farolito as the best burrito I'd ever had. Imagine the satisfaction of moving somewhere because of a restaurant's burritos only to find out there's one with even better burritos! This is elevating my mood.
If I want to mix it up a little, or if I'm with some hoighty toighty friends, I can also go to the Papa Lotte. It's a little more fancy, but still very good. There's also this veg-friendly joint right by Still Flyin' manager Big Brah's place. I can't remember the name, but damn they sure have great camarones burritos there. One place that a lot of people swear by is called Pancho Villa, but I don't get it. Compared to ever a place as good as Barburritos it is a treat from the heavens, but it's not on the same level of the ones already discussed.
Dark, one thing that takes the burritos over the edge over here is the avocado, my favorite ingredient. If you don't like guac, I don't think you'd like avocados, which is something I will never understand. Also, why in the fucking hell had you never eaten a burrito before you moved to Boston? I've experienced several burritos in Boston and they are better than ones in Georgia.
Last thing: the Taco Stand burritos taste like something you buy at a gas station and put in the microwave. I will never understand why some people think that is food. They are the worst burritos I've ever had in my life, and a trip to SF is in great need if you are living your life this way.
