I moved to Seattle four years ago from Southern California (LA area), and my girlfriend has been here for 7 years now (originally from San Diego). After having looked far and wide for several years now, both independently and as a couple, we can say without a doubt that El Puerco Lloron is *the* best mexican food in Seattle. Handmade tortillas to order should be enough, but in case it's not: it's well-priced, the older hispanic couple that owns it is totally awesome and very nice, they have all the legitimate-actual-mexican dishes you could want, you can see the water from their giant windows, and everything (not just the tortillas) is mega fresh. Cannot recommend highly enough.
