El Ruso

If you're looking for pura calidad, you're in the right place. Taquero Walter Soto's Echo Park taco trailer is one of L.A.'s most popular spots for perfectly tender mesquite-grilled meats and just-bubbled flour tortillas, and it operates under that slogan—and man, does it deliver. During the week you can find Sinaloa-style specialties (including corn tortillas, tripitas and tostadas), but from Friday to Sunday you can get El Ruso's OG menu: The Sonora-style grilled meats stuffed into fresh flour tortillas for some of the heftiest, hottest, most flavorful tacos in L.A.
