Like its East Colfax and South Broadway siblings, this Tennyson Street go-to for biscuits by day, Fat Sully’s pizza by night, and cocktails anytime stays open until 1 a.m. Thursday through Saturday and 11 p.m. the rest of the week. Loaded garlic knots, pies by the slice or the 26-inch whole, craft drafts, and iced vodka lattes all patiently await.

To call Occidental a punk-themed dive is to do a disservice to this little sibling of Williams & Graham, bartender Sean Kenyon’s celebrated cocktail destination next door. While it most certainly is that, it exudes a witty charm that elevates both its decor and its menu. Serving food until 1 a.m. and drinks until 2 a.m., the crackerjack crew whips up original drinks laced with everything from dill-infused aquavit to green bell pepper and celery bitters, which pair with an array of easygoing but well-made snacks: green-chile mac and three cheeses, say, or spiced chicken tenders with lemon-parsley tahini sauce.

With operating hours extending until 11 p.m. Monday through Thursday and to midnight on Friday and Saturday, the RiNo outpost of this popular East Coast–based tapería buzzes right up to closing time: Any reveler here will tell you there’s always one last sip of Cava or sangria to be had, one last bite of paella or flan.

Nightly until midnight, this RiNo original shucks oysters, slings pizzas, and serves up spritzes and craft suds (among other things) in a 640-square-foot shipping container. Chicken-liver mousse, clam pizza, and a Fernet-and-Coke cocktail make for a classic Cart-Driver combo.

The Ballpark sibling of this Cherry Creek institution tricks out its famous burgers with all the à la carte fixings — chicharrones, PB&J, cream cheese, Fritos, sauerkraut, and more — until 11:45 p.m. Throw in pretzel knots with queso, onion rings, and spiked milkshakes for a balanced meal.

Euclid Hall’s old space could now almost pass for some hip lounge in Shanghai, all red lanterns, neon, and street-style murals (plus QR code–driven service). Though closing time depends to some extent on business, both the upstairs Tea Room and downstairs Tap Room generally offer their funky Asian fusion fare — take the burger sliders on bao buns called In-n-Băouts, whiskey-spiked drunken noodles, or hamachi sashimi in truffle vinaigrette — until 10:45 or 11 p.m., while the bar pours cocktails like the Cognac- and Sherry-based Slums of Shaolin and the Trigger Warning with baijiu, Alpine herbal liqueur, pineapple, and ginger until midnight.

On Fridays and Saturdays, Uptown’s favorite pan–Asian lounge and ping-pong hall serves up dumplings, stuffed bao, ramen, and more alongside sake flights and Volcano Bowls until 11 p.m. (Meanwhile, Ace’s retro diner–inspired sibling Steuben’s next door keeps its comfort-food staples — fried pickles, deviled eggs, meatloaf, BLTs, and so on — coming on the same clock.)

OPEN, a stellar sandwich shop that launched in March at American Bonded, recently took over the kitchen in this Congress Park fixture, where it lives up to its name until 11 p.m. on Fridays and Saturdays. With $1 going to a good cause (such as Project Angel Heart), each sandwich was created by a different local chef — from the Osaka with chicken karaage, ginger-sesame slaw, and oshinko on shokupan to the Lee, featuring Sichuan braised beef and provolone on a baguette with Sichuan-peppercorn dipping broth; also on the menu are smoked ribs, starters and sides like French onion dip with homemade potato chips, and sweets such as salted shortbread.

When Frank Bonanno took over this Cap Hill dive bar several years back, many expected him to make it fancy; instead, he preserved its low-key neighborhood soul (while improving its F&B service). Juicy Lucys and sloppy joes, pita sandwiches stuffed with shaved lamb and fattoush or saganaki and pesto, and classic cocktails on tap along with Colorado craft drafts elicit good cheer until 2 a.m.

This colorful yet white-hot cocktail lounge in Cherry Creek serves up soirée-worthy hors d’oeuvres until midnight Sunday through Thursday and 1 a.m. Friday and Saturday. Live large over caviar service and lobster rolls, or keep it (relatively) simple with fava bean hummus and crudités or a soft pretzel accompanied by Gouda fondue.

Come last call, locals know that all roads lead to this true-blue 24/7 diner. French dips and New York strips, pancakes and pork chops, black coffee and hot chocolate — it’s all here, all night (and day), in a picture-perfect setting of wood-paneled walls, orange vinyl booths, and stained-glass pendant lamps.

For decades, this critic-proof University institution has curbed students’ cravings for traditional Middle Eastern specialties until 5 a.m. on Fridays and Saturdays, 4 a.m. the rest of the week. There’s no hangover that falafel, shish kabobs, and baklava can’t cure.

The first of two K-pubs listed here (see also DMZ below), this absolute banger is open until 2 a.m. Tuesday–Sunday, which means nightcrawlers have got all the time in the world to get their fill of its fabulous anju (the Korean term for bar food). That includes army stew, a postwar dish of ramen noodles, kimchi, and American meats such as hot dogs; tteokbokki with dumplings or blood sausage; corn cheese, which is just what it sounds like; fried chicken with garlic-butter sauce; roe soup and snail salad; and so much more — all tailor-made for washing down with banana-flavored makgeolli, pineapple-vinegar soju, and other fermented and/or distilled rice beverages.

Open until 2 a.m., this dim-lit, family-run K-pub in an Aurora strip mall offers a menu and drink list similar to that of Thank Sool Pocha, but eagle-eyed eaters will spot a few new things to try, including addictive semi-dried squid with dipping sauce and a choice of either sweet-and-spicy or “very spicy” wings.
