I just had some fish tacos from a guy who has a mini-stand set up in front of the laundromat across from the Casbah Cafe on Sunset and Hyperion. He is selling fish and shrimp tacos, Ensenada-style for $2.50.
They are the first fish tacos I've had in LA that compare favorably to the Tacos al Fenix stand in Ensenada, which is my gold standard. Incidentally, his name is Ricardo and he is from Ensenada.
He is planning on being there Thursday through Saturday in the Evenings and Sunday in the late afternoon/evening.
