The best tacos?

Hard to say if they're the best, but Taqueria El Grullense in Palo Alto has some pretty amazing tacos. I have no idea what "El Grullense" means (go ahead, try looking it up), but it doesn't really matter when you're really hungry and have a thin wallet! At $1.75 each (meat tacos are somewhat cheaper), a complete meal with ice cold bear can be had for a mere $6.50. And they pile the extras on with such a heavy hand that you can't really tell where one taco ends and the other starts. Good deal. The best part? It's just down the road from my house. Yay, I've found my new taco heaven. Where do you go for the best tacos?
