Denver has been light on Spanish cuisine and all but devoid of Portuguese specialties — but at the end of 2017 it got a heavy hitter when Jennifer Jasinski and Beth Gruitch opened Ultreia inside Union Station. Even if we were awash in the food of the Iberian Peninsula, though, this jewel box of an eatery would stand out for its imported hams and cheeses, spot-on pintxos, tapas and petiscos (all manner of appetizers) and loving treatment of meats, whether steak, lamb, seafood or pork. Herbal gin-tonics (the Spanish leave off the ampersand) in various blends augment a drinks menu that also exalts sherry and rare red and white wines from Portugal and Spain's wine-producing regions. A seat at the bar to watch a four-year aged jamón Ibérico get carefully carved into succulent slivers is just the right place to absorb the ambience and feel like an international traveler.

Chef Jesse Vega thrilled the LoHi neighborhood with upscale bites at Central Bistro & Bar, but he and the restaurant's owner, Isiah Salazar, were ready to switch things up last summer. The result is just as hot as its predecessor (there's still the enormous "HOT" sign over the kitchen), but focuses on Mexican cuisine and the food of Vega's Puerto Rico. Plantains make multiple appearances — in several styles of mofongo, as plantain chips to go with a glorious guacamole, and as a stand-in for lasagna noodles in a dish called pastelon, which alternates plantain strips with layers of picadillo, mozzarella and salsa criolla. Puerto Rico is an island, so seafood also stars in zippy ceviches and a softshell crab sandwich. Vega pours his heart and soul into his mushroom and chicken empanadas, using his grandmother's recipe to capture the spirit of Puerto Rico on a plate.

Old South Pearl Street has the market cornered on Japanese cuisine. Here you'll find three restaurants all owned by the Kizaki brothers, all devoted to absolutely quality ingredients and authentic dishes. Choose Sushi Den for seafood, Izakaya Den for stunning architecture and small plates or Ototo for a more intimate experience, not to mention robatayaki — skewered meats and vegetables grilled over charcoal. Our favorite of the three is Ototo, which is smaller in size but offers a little of everything on the menu, whether you're in the mood for expertly sliced sashimi, a rich bowl of ramen, or Japanese specialties like whole grilled squid, skewered chicken gizzards and hearts, or hamachi collar perfumed with mesquite. With more than thirty years' experience serving the food of their home country in Denver, Toshi and Yasu Kizaki still know how to keep things fresh.

When Bamboo Sushi first landed in Denver from Portland, it operated out of a stall at Avanti Food & Beverage, giving the city a tantalizing taste of its sushi. It initially garnered praise mostly for its sustainable sourcing; Bamboo's deep commitment to good ocean stewardship is particularly admirable in a category that relies heavily on over-fished specimens. But that stall turned out to be a rather limited glimpse of the restaurant's capabilities. Bamboo's permanent LoHi location is sleek and modern, with a wide-ranging list of sushi served both traditionally and innovatively, a well-rounded sake list, and an array of izakaya fare that carries Bamboo's sourcing commitment from water to land. Also worth noting is Bamboo's omakase, for which you can set your own price. It feels like a steal, especially paired with the Wednesday night deal on sake, when every single bottle is half price.

Cattivella means "naughty girl" in Italian, but the only naughty thing about chef-owner Elise Wiggins is that she didn't open her own place sooner. With an approachable menu of shareable plates (think buffalo burrata and flatbread), wood-fired pizzas, entrees and scratch pastas, Cattivella captures the heart and soul of Italy, a country that Wiggins knows well. And since she's a constant presence in the restaurant, no dish goes out without her stamp of approval. With a bustling open kitchen and wrap-around chef's counter, Cattivella, which opened last year in Stapleton, has a convivial vibe, one that spills to the spacious patio when the weather is warm. This is a place where friends greet old friends and newcomers make new ones, all while savoring agnolotti and drinking great wine.

Romano's is truly old, old-school Italian. Neil Romano moved to Denver from Manhattan (bringing some of mother Carmela's recipes with him), and in 1967 founded a three-table pizzeria in Littleton with his wife, Ellie. Over the years the restaurant has expanded in both space and scope, adding liquor and many of those classic dishes, redolent with the garlic that was key to Carmela's spaghetti sauce. Today a third generation of Romanos work the kitchen and the charming dining room, filled with regulars who consider themselves part of the family. That family's motto: "Every day we are grateful for la dolce vita — the sweet life we have found here." And we're grateful they did.

For a chef who's been in the restaurant business as long as he has, Radek Cerny still manages to bring a sense of fun and whimsy to some seriously French cuisine. Papillon, for example, was a smash hit in Cherry Creek before many of today's hot young culinary stars had tasted their first frites. The chef returned to Denver in 2017 after years of serving dinner in Boulder, putting Atelier in the original Il Posto location in the Uptown neighborhood. Here you can luxuriate in rotating classics like duck rillettes, escargot, foie gras and lobster, but Cerny also has a way with such Western favorites as elk (look for wapiti on the menu), Alaskan salmon and bison short ribs. Be sure to bring a few extra bucks for a bottle of wine; the list here is dazzling, and the food is built to match with the best of Burgundy and Bordeaux.

Vibrant vegetarian cooking is about far more than tofu and seitan. Boulderites have long been focused on meat-free dining, so they're a tough lot to impress. Leave it to Leaf to rise above the competition and provide modern, international and inventive dishes that folks actually crave. The restaurant has its own farm, so produce is at its best during Boulder County's growing season, but the kitchen supplements locally grown goods with a worldly roster. Enchiladas are stuffed with jackfruit carnitas, fried chicken is reimagined with meaty king trumpet mushrooms, and sweet-potato gnocchi are dressed with jewels of fava beans, winter squash and nutty pesto. No matter what you order, every bite is alive with the seasons of Colorado.

There may be many fish in Denver's sea of seafood restaurants, but Stoic & Genuine is a real catch. Pull into this Union Station eatery for gleaming oysters, craveable crudos and fabulous fish. If you need a quick lunch, the seared albacore tuna melt on an English muffin or the fish and chips could be just the ticket, but make the return trip for dinner and spoil yourself with caviar service, a seafood tower (bring friends!), or one of Denver's most decadent dishes: the "Surf in Turf," a miraculous melding of New York strip and ahi tuna swathed in a silky black truffle Hollandaise. Don't quite have your sea legs? Buck the trend as all around you slurp shellfish by tucking into S & G's masterful double cheeseburger.

Angelo's Taverna bills itself as Denver's original pizza and oyster bar — and given that it's been serving central Denver since the Nixon administration, it's safe to say that it's the longest-running restaurant of its ilk. While it was refurbished by new owners in 2013, Angelo's is still all dark woods and stained-glass windows, with the kind of labyrinthine floor plan that suggests the restaurant was built before breezy, cavernous dining rooms became the norm. Oysters still anchor the menu here, and Angelo's offers a rotating menu of mollusks that changes with what's fresh. We're half-shell people, but the restaurant makes a compelling argument for a char-grilled preparation: Your order of a half-dozen can be dressed up with garlic butter or bacon and Gorgonzola. Belly up to the bar during happy hour for $1 East Coast or West Coast oysters, or have them char-grilled for a dollar more.
