Waiting for someone to mention Tacos El Gordo... haven't tried them yet but I hear they're the best in the East Bay..
Anyone tried Sancho's taqueria in Palo Alto? Hear they good too. I can't fuck with El Greasy (El Grullense) they always fuck up my order, and it just wasn't that good. Redwood has like 3-4 locations, hella Michoacan paisas everywhere too. PURO SINALOA putos!
I think the best burrito spot in SF is in Bayview, called El Azteca, you can order Chipotle style, I usually get the streak and prawn burrito with refried beans, red rice, sour cream, mild salsa.. hella good! best tacos in SF probably La Laguna on 3rd Street in Hunters Point. Taco Tuesdays .99 cent tacos, you can taste the beer they use to marinate the taco meat too. I think that all the taquerias on mission are overrated a bit. Farolito is only good for late night. I'd take Guadalajara over Farolito. There's also this spot on mission called La Oaxaquena, BEST Mexican Hot Chocolate and Chicken Mole tamales. The owner personally goes to Mexico and brings back raw cocoa.
Any of the SJ peeps on here tried that Mexico Bakery tortas on Tully or Story I think? Supposedly the best Tortas in the whole Bay.
