When we last saw Taqueria Nueve back in 2008, it was the harbinger of adventurous Mexican cuisine in Portland. Nueve had excellent house margaritas, bold ceviche, and edgy boar tacos. Fast-forward eight years (get the backstory here): chef/owner Billy Schumaker has returned (this time inside the old Beaker & Flask space at 727 SE Washington St), offering the same undiminished plates and colorful, family-friendly vibe without skipping a beat.
