La Sirenita (2817 NE Alberta / 503-335-8283) is a taqueria that serves up some of the most authentic Mexican food you’ll find in Portland. Cheap and tasty, most items on the large menu are under $5 and tacos go for $1.50. It’s often crowded but it’s worth the wait - the basic interior and lack of atmosphere only underscores how good the food is. Munching on some tacos al pastor will quickly transport you and your taste buds out of the drizzly Portland rain to a sunnier and spicier place.
