Top 10 Coolest “Theme” Bars in Denver

Denver has plenty of normal bars. You know the type: exposed brick, a fern struggling for its life, one Edison bulb hanging over a $17 cocktail named after a mining claim.

Fine. Great. We love ambiance.

But sometimes you want more. Sometimes you want a drink served in a skull, a secret door, a horror movie, a pinball machine or a room that makes you question whether you accidentally joined a very committed theater troupe.

So here are some of the coolest theme bars in the metro Denver area, from tiki chaos to hidden cocktail dens to late-night dance caves where your “one drink” plan quietly dies in an alley.

1. Hell or High Water Tiki

Theme: Maximalist tiki, camp, chaos, rum-fueled vacation brain
Best for: Group nights, birthdays, “I need to be somewhere that looks like a pirate hallucination.”

Hell or High Water Tiki is one of Denver’s better-known themed bar picks, and for good reason. It does not whisper its theme. It screams it through a flaming pineapple while wearing a floral shirt and possibly holding a sword.

This is the kind of bar where the decor is not simply decor. It is an ecosystem. The whole thing feels like a tropical storm hit a pirate ship, then everyone involved decided to add more rum and call it design.

Go here when you want the drink to arrive looking like it requires both a garnish and a structural engineer.

Vibe check: Big, loud, colorful and ideal for groups that want to feel like they took a vacation without getting absolutely bullied by DIA security.

2. Williams & Graham

Theme: Speakeasy hidden behind a bookstore
Best for: Dates, visitors, cocktail nerds, people who say “mouthfeel” unironically

Williams & Graham is probably the first place a lot of people think of when they hear “Denver speakeasy.” You enter through an unassuming bookstore setup, then a bookcase opens into the actual bar because apparently doors were too emotionally available.

The drinks are serious, the lighting is flattering and the whole thing still works, even though everyone and their cousin knows about it now. That is the thing about a good gimmick: If the cocktails are good enough, it stops being a gimmick and becomes “ambiance.”

This is a reliable “impress someone” bar. Date, out-of-town friend, boss you need to tolerate for 90 minutes — whatever the situation, Williams & Graham can handle it.

Vibe check: Classic Denver speakeasy. Still one of the safest picks when you want someone to think you planned ahead.

3. Retrograde

Theme: Hidden cocktail bar/freezer-door speakeasy energy
Best for: Low-lit drinks, date night, showing off without being too obvious

Retrograde has that “I know a place” feel, which is annoying only because it works.

The whole hidden-bar setup gives it the right amount of mystery without requiring you to solve a murder or recite a password from a 1920s telegram. It is low-lit, moody and cocktail-forward, which makes it a strong date-night move or a solid second stop when you want to keep the night going somewhere that feels cooler than wherever you started.

Retrograde is also commonly included in Denver themed-bar conversations, especially for people who like the speakeasy format but want something a little more under-the-radar than the obvious heavy hitters.

Vibe check: A good “let’s go somewhere interesting” option that does not feel like you are trying too hard. You are, of course, but the bar is helping you hide it.

4. Slashers

Theme: Horror bar
Best for: Halloween people, horror fans, campy cocktails, goth-adjacent hangs

Some people wait until October to get spooky. Those people lack commitment.

Slashers is Denver’s horror bar, built for people who think fake blood, scary movies and themed cocktails are a year-round lifestyle choice. It leans campy, creepy and fun rather than “someone is definitely living in the walls,” which is appreciated.

This is a great stop for horror fans, Halloween people, alt crowds or anyone who prefers their bar atmosphere with a little theatrical menace. It is also a strong choice for a themed night out that does not involve pretending you understand the difference between three kinds of amaro.

Vibe check: If you want spooky without waiting until October like some seasonal coward, this is your move.

5. Adventure Time Bar

Theme: Playful, immersive cocktail bar
Best for: Creative cocktails, not-too-serious date night, groups that want something new

Adventure Time describes itself as a Denver cocktail bar with ambitious drinks, genuine hospitality and a night that “never takes itself too seriously.” Honestly, that is a pretty good sales pitch in a city where some bars act like ordering a drink is a graduate seminar.

The theme here is playful and immersive without feeling like you accidentally wandered into a children’s birthday party with better bitters. It is a good pick for creative cocktails and nights when you want something fun, but you are not necessarily trying to scream over a DJ or get emotionally invested in a jukebox.

Vibe check: Good for people who want technique without the bartender making eye contact like they are about to explain vermouth for 20 minutes.

6. Adrift

Theme: Polynesian/tiki escapism
Best for: Rum drinks, tropical moods, pretending Denver has an ocean

Adrift is Denver’s South Broadway tiki staple, and it brings the full tropical escape without asking you to forget you are still very much in landlocked Colorado.

Compared with Hell or High Water, Adrift feels a little more classic tiki lounge and a little less “haunted pirate ship had a fever dream.” Expect rum drinks, island-inspired decor and the kind of mood lighting that makes everyone look like they are making better decisions than they are.

It is a strong pre-dinner, date-night or “I need to be somewhere that is not beige” kind of place.

Vibe check: Less pirate hallucination, more vacation with better glassware.

7. The 1UP Arcade Bar

Theme: Arcade bar
Best for: Casual hangs, pinball, nostalgic button-mashing, dates where conversation needs backup

The 1UP is what happens when someone correctly realizes that adults also deserve arcade games, only now with beer.

With classic games, pinball, skee-ball and enough buttons to make your inner 12-year-old start negotiating for quarters, The 1UP is one of Denver’s easiest group bar picks. It works for casual dates, birthdays, after-work hangs and any situation where you want built-in entertainment because conversation can only carry some people so far.

There are multiple locations, so check which one makes sense before everyone starts confidently driving to different parts of town. A shocking number of group plans die this way.

Vibe check: Great if you want to drink and lose at skee-ball with dignity. Or without dignity. Denver supports both.

8. Milk Bar

Theme: Multi-room club/bar with retro, goth, industrial and dance-floor personalities
Best for: Late nights, dancing, alternative crowds

Milk Bar is not the place you go for a quiet little martini and a thoughtful chat about real estate. Milk Bar is where a normal night goes after it has made several questionable but enthusiastic decisions.

The multi-room setup gives it a choose-your-own-adventure feel, with retro, goth, industrial and dance-floor energy depending on the night and the room. It is a mainstay for late-night crowds, alternative scenes and people who left the house dressed like they actually meant it.

If you are looking for a themed bar that leans more club than cocktail lounge, Milk Bar belongs on the list.

Vibe check: Not a quiet cocktail spot. More of a “we went out for one drink and now it is 1:37 a.m.” situation.

9. Bernard’s Tiki Room at Arvada Tavern

Theme: Tiki speakeasy-style bar in Arvada
Best for: Tiki without going downtown, date night, suburban escapism

Bernard’s Tiki Room at Arvada Tavern is a great reminder that not every cool themed bar requires sacrificing your evening to downtown parking.

This Arvada spot gives you tiki atmosphere with a speakeasy-style twist, making it a strong choice for northwest metro drinkers or anyone who wants a themed cocktail night without turning the logistics into a federal project.

It is especially good for date night, double dates or that very specific mood where you want to feel transported but still be within a reasonable distance of your car.

Vibe check: A strong Denver-area option if you are northwest of town and do not feel like donating your evening to parking.

10. The Cruise Room

Theme: Art Deco martini lounge
Best for: Classic cocktails, history, pre-dinner drinks downtown

The Cruise Room is not as loud or gimmicky as some of the other bars on this list, but it has something better: actual style.

Located in the Oxford Hotel downtown, The Cruise Room leans into Art Deco elegance, old-school cocktails and a historic atmosphere that does not feel like it was ordered in bulk from a theme-bar supply catalog. It is sleek, classic and a little glamorous in that “let’s have one proper drink before dinner” kind of way.

If you want neon skulls, go elsewhere. If you want a martini in a room that knows exactly what it is doing, this is your spot.

Vibe check: Not gimmicky, just cool. A rare and fragile resource.

If You’re Planning the Night

For a date

Start at Williams & Graham or Retrograde. Both have enough atmosphere to make it feel like you tried, but not so much that it looks like you created a full itinerary in a notes app titled “Operation Charm.”

If the date is going well, you can always end somewhere louder. At that point, you have both decided personality is optional.

For a group

Do Hell or High Water Tiki or The 1UP. Groups need visual stimulation and activities, otherwise someone starts talking about their job.

Hell or High Water gives you the big themed cocktail chaos. The 1UP gives you games, competition and the opportunity to learn which of your friends gets weirdly intense about pinball.

For spooky or alt vibes

Start at Slashers, then move to Milk Bar if the night needs to escalate. This is not a quiet evening. This is a “we are making decisions in eyeliner” evening.

For visitors

Take them to Williams & Graham or Hell or High Water. Both feel specific enough that nobody can say, “We have something like this back home,” which is the entire point of taking visitors anywhere.

For tiki fans

Do Adrift for the more classic South Broadway tiki mood, Hell or High Water for maximalist chaos or Bernard’s Tiki Room if you are closer to Arvada and downtown sounds exhausting.

Final Sip

Denver’s theme bar scene is strong because it covers the full emotional spectrum: spooky, tropical, secretive, nostalgic, historic, chaotic and “why am I dancing in this room at 1 a.m.?”

That is the beauty of it. You do not have to settle for a plain bar unless you want to. And honestly, with this many secret doors, tiki drinks, arcade cabinets and haunted cocktails within reach, “plain” feels like a personal failure.

As always, check hours, reservation policies and event calendars before you go. The only thing worse than showing up to a closed bar is doing it in a themed outfit.
