Lively Spanish tapas inside Union Station with standout small plates and cocktails; prices add up and some service/value complaints exist, but most diners leave happy.
Ultreia delivers solid A-grade performance through exceptional food quality—bacon-wrapped dates, croquetas, and ribs earn consistent praise—paired with warm, attentive service. The iconic Union Station setting enhances appeal, though cramped main-level seating and occasional ventilation issues prevent grade A territory. Tapas format and premium imports can inflate bills, but overall execution competes well with Denver's better neighborhood restaurants.
Inside Denver Union Station, Ultreia buzzes with lively tapas energy—servers weave through the small room while plates land fast and the bar hums. One diner called the dates and deviled eggs "the kind that stop conversation," and another praised the warm, stylish vibe. A few guests note smoke from the open kitchen that can linger on clothes, but most highlight friendly, attentive service and the convenient setting. The cooking leans Iberian with contemporary twists: classic croquetas, patatas bravas, and gambas sit alongside a baharat-seasoned burger, chili-crisp salmon from the tinned list, and a memorable crispy trout sandwich. Expect focused menus where ordering a few plates is ideal; prices feel fair to many, though tapas can add up quickly and premium imports raise totals. Best bets repeat across reviews: bacon-wrapped dates, croquettes, ribs, and fries with aioli. Families do fine here thanks to approachable options like fries, the burger, corn toast, and mild tapas, though there is no explicit kids menu. For picky eaters, stick to simpler plates and avoid spicier sauces; adventurous diners will enjoy the tinned fish and charcuterie section. Noise is lively, so expect casual rather than hushed family dinners.
