check out this web site i found that rates San Francisco Super Burritos
http://www.burritoeater.com/main.php I have now ate nothing but super burritos for 2 weeks. every day a different place. Yesterday I ate the biggest super burrito ever at this el salvadorian place Los Guanacos 4479 Mission & Francis across the street from my pad, after wards I couldn't move, in fact I still can barely move. I'm thinking they make the best and biggest super burrito in the city. Today I ate a tiny little wanna be super burrito from Taqueria Cancun. Taqueria Cancun can suck it! If it wasn't for vegetarian burrito eaters, and their misguided hipster friends, and visiting people actually from Cancun trying to find a place with food like their homeland nobody would ever go to that chain!
