I've had good burritos elsewhere, but I've been burned many times. So it's possible to find a good burrito, but it's like 1 in 10 chance of getting a good burrito at best. It's easier to find a good burrito outside of cali than it is to find a good bagel outside of NY for some reason, though.

I live in the Central Coast area, so I'm neutral in the SF vs. SoCal burrito war - I like them both.
