How late are the bars at Wynn Las Vegas open?
Here is the straight answer: B Bar is open 24 hours a day, while Delilah serves dinner daily from 5 to 10 p.m. and offers late-night dining from 10:30 p.m. to 1 a.m. Thursday through Saturday. Delilah’s Little Bubble Bar keeps separate hours, operating daily from 4 to 10 p.m.
One naming detail matters when you are planning the night. Wynn does not list a separate lounge called “B Cocktails.” On Wynn’s dining pages, “Cocktails” is the category attached to B Bar, not the name of another venue. If you are looking for the bar that never closes, B Bar is the place you want.
Back where I’m from in the Midwest, a bar open around the clock would raise at least three questions from the city council and probably require a pancake breakfast fundraiser. In Las Vegas, it is simply another practical option. Still, these two Wynn destinations serve very different purposes. B Bar is the flexible, any-hour stop. Delilah is the dressed-up supper-club experience that can carry a properly planned evening past midnight on select nights.
B Bar is Wynn’s true 24-hour cocktail option
B Bar sits inside the Wynn casino beside the Fairway Esplanade. Wynn lists it as open 24/7, making it the dependable answer when a show runs late, a flight arrives at an odd hour, or the group decides bedtime is merely a suggestion.
The atmosphere is more polished hotel bar than sports pub. Wynn describes a room shaped by mahogany accents, crystal lighting, custom furnishings, and warm colors. Its location near the casino gives it energy, but the concept is built around cocktails and conversation rather than televisions, wings, or game-day noise.
That distinction also applies to the menu. B Bar does not serve food. Wynn’s late-night guide specifically identifies it as a drinks-only venue, with cocktails, whiskey, wine, coffee, tea, juice, and other nonalcoholic choices available. Anyone expecting burgers and fries at 4 a.m. should make a food stop before settling in.
What should you expect at B Bar?
The official description emphasizes reimagined classic cocktails, including the Old Fashioned. That makes B Bar a sensible destination for someone who wants a carefully prepared drink without needing a reservation or building the entire evening around one seating time.
There are two practical rules to remember. B Bar is restricted to guests 21 and older, and a valid government-issued ID is required. Wynn also specifies resort-casual attire. That is not the same level of dress expected at Delilah, but this is still Wynn. The old college hoodie that survived three moves may deserve a quiet night back in the hotel room.
- Hours: Open 24 hours daily.
- Location: In the Wynn casino, adjacent to the Fairway Esplanade.
- Food: No food service.
- Age requirement: Guests must be 21 or older with valid government-issued identification.
- Dress code: Resort casual.
Delilah combines dinner, cocktails, and late-night entertainment
Delilah is not simply a bar with later hours. It is an American fine-dining supper club inspired by the showrooms and supper clubs of 1950s Las Vegas, with Art Deco details, live performers, multiple levels, and a menu built around American classics. Wynn places it in the Tower Suites enclave, adjacent to Wing Lei and across from the Rolex boutique.
Regular dinner service runs from 5 to 10 p.m. daily. On Thursday, Friday, and Saturday, Delilah adds late-night dining from 10:30 p.m. until 1 a.m. That schedule makes it a legitimate after-hours choice on those three nights, but it requires more planning than B Bar.
The menu includes seafood, steaks, Beef Wellington, Delilah’s chicken tenders, and other supper-club dishes. The experience also incorporates musicians, vocalists, tableside presentations, and cocktails, so this is a destination where dinner is meant to be the evening’s main event rather than a quick refueling stop.
How does Little Bubble Bar fit into the evening?
Little Bubble Bar is Delilah’s intimate entry lounge, with five tables available on a first-come, first-served basis. Wynn lists it as open daily from 4 to 10 p.m., which makes it useful for a drink before dinner but not the part of Delilah that continues until 1 a.m.
The lounge focuses on cocktails and canapés in a setting inspired by old Hollywood. Because seating is limited, it is not the sort of place where a large group should arrive expecting to spread out like it owns the county fair beer tent.
Delilah’s dress code is upscale casual chic. Children under 12 are not permitted, and the venue becomes restricted to guests 21 and older after 7 p.m. Reservations are available through Wynn and are the sensible approach for dinner, particularly on nights with late service.
- Dinner: Daily from 5 to 10 p.m.
- Late-night dining: Thursday through Saturday from 10:30 p.m. to 1 a.m.
- Little Bubble Bar: Daily from 4 to 10 p.m.
- Dress code: Upscale casual chic.
- Age policy: No children under 12, with entry limited to guests 21 and older after 7 p.m.
Which Wynn late-night stop fits your plans?
Choose B Bar when timing is the biggest concern. It is open around the clock, does not require you to coordinate dinner service, and works equally well for a midnight cocktail or an unusually early morning coffee. Just remember that it does not serve food.
Choose Delilah when you want dinner, entertainment, and a full supper-club production. For the latest experience, plan around Thursday through Saturday, when late-night dining continues until 1 a.m. On other nights, regular dinner service ends at 10 p.m.
The key is not to treat the names or hours as interchangeable. B Bar is the all-hours cocktail lounge. Little Bubble Bar is Delilah’s small pre-dinner lounge, open until 10 p.m. Delilah itself is the venue with late-night dining until 1 a.m. on three nights of the week.
Hours can change for special events or resort operations, so checking Wynn’s official venue pages on the day of your visit is always smart. That may not sound as adventurous as wandering the Strip and trusting fate, but neither does showing up hungry at a bar with no kitchen. A little planning keeps the night fun, which is the whole point.
