What It Is
Weltraum is a bar, gallery, and performance venue all at once. The name — German for "space" — signals the register: this is not a conventional bar with art on the walls, and not a gallery with a beverage service. It's genuinely both, in equal measure. Four founders built it together and did the renovation themselves, which shows in the kind of detail you notice when you're actually in the room.
The space opened in May and operates Wednesday to Saturday evenings. There's no website, no booking system, no event calendar — just Instagram and word of mouth. That kind of low-visibility operation usually means either it won't last or it becomes the kind of place people actively protect by not shouting about it.
The Four Founders
Maron drives the concept and is an artist himself. Tom brings gastro experience. Felix is an actor. Markus handles the legal side. The mix is deliberate — different perspectives, different skills, different reasons for being there. They wanted to create something that didn't feel like a designed product, something that could grow and change. The renovation itself was done by the team, which is why the space has texture: reclaimed materials, custom details, a sense that this was built by people who cared about the specifics.
The Drinks and the Room
Cocktails are made with fresh-pressed juices — rote Rübe, Karotte, Zitrone, Granatapfel. Not pre-bought, not convenience. That philosophy extends to the whole operation: intention over efficiency. There are plans for small snacks (Pastrami sandwich, Mozzarella and tomato), and eventually a regular brunch.
But the real point is the room itself and what happens in it. Art rotates on the walls. Vernissages and finissages are planned — two of each per month. Musicians, performers, and people with their own formats can use the space. The bar prices are standard — this isn't a premium cocktail spot — and the point is the community that forms around it.
The 4th District Angle
Wieden (the 4th) has been quietly building something over the past few years. It's not the 6th or the 7th — it doesn't have that established independent-cultural-scene reputation yet. But there's a texture emerging: small galleries, artist-run spaces, venues that opened because the founders believed in the neighbourhood, not because the rent was cheap. Weltraum fits that pattern exactly.
In the margin
Komm als Alien, geh als Freund.
That's the motto. It's the kind of thing that could sound cheesy, but in this context it lands — a space where different people actually do come together and something real happens.

Kapitel Zwei Wine — 10-winery Vienna pop-up, end of July
- When
- 25 July 2026 – 31 July 2026
Chris Sciacca spent 25 years in corporate communications in New York before pivoting to viticulture. He completed a degree at IMC Krems in 2024 and now runs Kapitel Zwei Wine, an organic microwinery in the Kremstal growing French varietals rare to Austria — Chenin Blanc, Roussanne, Sémillon — aged in 55-litre Italian amphora. He's previously organized two consecutive pop-up wine bars in Paris with 27 Austrian wineries; the Vienna edition brings the format home. This July, Kapitel Zwei is hosting a free 10-winery pop-up in Vienna. Exact date and venue are still being finalized — contact chris@kapitelzwei.wine for details before the event.

- When
- 17 June 2026 – 31 July 2026
- Where
- 7th · Neubau
Francesco Fusaro, an Italian baker committed to sourdough and handcraft, has opened Altroché as a pop-up on Neustiftgasse 81 in the 7th. The range is proper Italian bakery: vegan cornetti, Bari-style focaccia, pizza slices, sourdough bread — all made on fermentation principles by one person. The 7th has no shortage of cafés, but a serious micro-bakery run on sourdough discipline is different. Fusaro plans a permanent Vienna location after the pop-up closes at the end of July. Open now through July 31.

- When
- 26 June 2026 – 31 August 2026
- Where
- 1st · Innere Stadt
Sekki is a three-month summer pop-up from Lucas 'Lucky' Shong and Jake Bergholtz, two of Vienna's most respected young chefs. They've taken over the evening service (Friday to Sunday, 6pm–midnight) at The Leo Grand's restaurant on Bauernmarkt 1 in the 1st district, running through the end of August. The menu is deliberately unpretentious — Kittseer sourdough, duck-butter, liver crème brûlée, Bergholtz's grandmother's apricot dumplings, Korean fried chicken — built from the network and experience both have accumulated across Vienna's best restaurants. The space itself is baroque and slightly kitschy; they're leaning into that rather than against it. It's the kind of kitchen that works best as a temporary thing, which is precisely why it's worth finding now.
