"Halcyon is a Warehouse District all-day cafe that opened in 2002, before the term “all-day cafe” even existed. It’s a calm coffee shop by day where you can get some work done, a cafe with breakfast and simple food options like panini sandwiches and salads, and a bar that’s open until 2am every night, with cocktails, wine, and beer. It’s right near a bunch of nightclubs, and it’s probably the place you’ve drunkenly stumbled into at 1:30am for their tableside s’mores." - nicolai mccrary, raphael brion
"A local café and bar that opened in 2017; its Aldrich Street location closed in August 2024 while its downtown location remains open." - Nadia Chaudhury
"An Austin cafe-and-bar known for its coffee, early-adopter espresso martinis, s’mores and dual daytime-and-nighttime service; the downtown outpost dates back to 2002 and the brand expanded into Mueller in 2017. The Mueller location at the listed address closed on Wednesday, August 14, while the original downtown location and other remaining addresses in San Antonio and Dallas continue to operate. The Mueller expansion coincided with a short-lived opening of a San Antonio–based pizza concept in the same area, and past locations in places like San Diego and Houston have since shuttered." - Nadia Chaudhury
"Open from the morning until 2 a.m., Halycon is a great place for a much-needed early morning or way late-night caffeine jolt (or coffee cocktails too). It's close to the shuttle at Republic Square. There are indoor and outdoor dine-in services." - Erin Russell, Nadia Chaudhury
"Halcyon is a Warehouse District all-day cafe that opened in 2002 before the term “all-day cafe” even existed. It’s like a Swiss army knife: A calm coffee shop by day where you can get work done or have a meeting with good espresso drinks (the beans are from Katz Coffee in Houston). It’s a cafe with breakfast like tacos and bagels, and then food options like panini sandwiches, salads, and even a dessert of tabletop s’mores. And it’s a bar that’s open until 2am every night. They also unironically serve a chocolate espresso martini, and there’s a good Happy Hour (and a reverse Happy Hour from midnight to close most nights). Sometimes you go to a bar for trivia, stand-up comedy, or a DJ, and other times you absolutely do not want such things, so check their website for the schedule. Halcyon operates with a theme of “let’s satisfy all the legal vices,” so in addition to caffeine and alcohol, they’re also on the nicotine beat: they sell cigarettes and cigars out of a humidor. There’s a smallish patio out front and to the side where you can hang out and smoke these cigars. It’s kind of divey in a way that a coffee shop/bar combo that opened in 2002 would be – it’s got a lived-in feel – but you notice it less at night. The area around Epoch can be very clubby, and late at night, people will often drunkenly tumble in there to get something to eat, especially the tabletop s’mores." - Raphael Brion
