OX Restaurant in Portland delivers an authentic Argentinian dining experience centered on wood-fired, smoky flavors. The menu shines with expertly grilled meats like ribeye and skirt steak, paired perfectly with vibrant chimichurri. Their fresh oysters from Washington, shucked with precision, offer a briny contrast to rich dishes like the smoked marrow bone with jalapeño and green onion. Signature plates such as the spicy braised beef tripe and octopus with mint aioli surprise the palate with bold yet balanced textures. Complementing savory bites include savory and cheese empanadas, coal-roasted artichokes with espelette mayo, and fried russet potatoes accented with horseradish aioli and dill. The clams chowder carries a deep, smoky richness that leaves a lasting impression. For dessert, the warm hazelnut torte with honey-chamomile ice cream and the house pineapple sorbet stand out as refined, refreshing finishes. OX skillfully blends rustic Argentine tradition with local Pacific Northwest ingredients, creating a memorable and sophisticated meal.
