Grelle Forelle

Massive disappointment. I went in expecting the best underground techno club in Vienna, but it didn’t even come close. Crowd: Awkward and noisy. No door selection, and people kept chatting on the dancefloor. Vibe: Felt off. Most people weren’t there for the music. The dancefloor is too bright, and having a massive bar right behind it completely kills the underground feel. Security: Overbearing. Security was everywhere, which destroyed any sense of freedom. I even got told to put my legs down while just chilling, never experienced that anywhere else. The one bright spot: The awareness team. Earplugs, snacks, fruit, and even deodorant; free of charge. It's not worth the hype in my opinion.

That was the most terrible club I've ever been. The music was boring, the staff was rude to us, yelled, and threatening us to be kicked out because we took one selfie which we didn't know it is forbidden. Bad music yet crazy expensive entrance ticket and everything is dirty. Not worth it at all! Not to mention lots of catcalling along the way to the gate. I've never been so unsafe, and not fun like this while going to Club. So disappointing. Yikes!

Awesome club! A lot of space, drinks not too pricy, good selection. A lot of Balkan people there which can be a good thing (especially for going out hehe)

We were there on Friday night. Great location, also very clean. It was fun until around 4 am when the music was not that good at any of the stages. The outside area is very pretty.

Huge and very solid underground club on the riverside . Lovers of underground techno will love it , also there are some procent of the "tourists" in t shirts because club does not have policy on dress code . But in general very good undreground club with good sound system and atmosphere was very good and cheerfull. For sure be coming back Next time when I am in Vienna

I think I caught a rather unfortunate evening there, as the U4 had some service disruption und the act on the Main stage was not my taste at all... so there wasn't too many people in the club at 2am on Friday night when we arrived. Apart from that we still had fun at the small side stage/DJ corridor. I will visit again some day and might very well give 1-2 stars more if it turns out I really just had unfortunate timing 🙏 It was no problem getting in, but 20€ was a bit pricey for what we got that night tbf.

This is an underground club with extra quality sound and light. Great for electronic music events. However, not everyone is going to like it due to its shape and narrow corridors...

Excellent sound, professional staff. Nice patio by the Donau canal. Getting there is a bit tricky, and you have to pass pushy dr0g dealers in deserted, dark alleyways. Ok drinks with Ok prices.

What's an American supposed to do on a Saturday night here in Vienna? Go out and party of course, what other answer is there to that question? Grelle Forelle was not on my hitlist when I was making my decision on where to go for the night but I'm glad I was recommended this place by a friend. The location is adjacent to the Danube River and to come out of the club at 5:30 in the morning and see the sunlight glistening along the water is an experience like no other. The surrounding area of the club was quite clean, at least cleaner than what I'm used to in LA in terms of pollution. When comparing the lighting and production of this venue to the larger clubs like Academy or Exchange in LA, it's quite lackluster. But Grelle Forelle is not a large club like the aforementioned, no, Grelle Forelle is the underground-style techno European club you've been hearing about all over social media. The light structures on the ceiling add an intricate geometric design that is noticeable yet minimalistic. The addition of smoke machines also adds to the industrial ambiance of an underground club. Admission was around 15 Euro which is cheaper than warehouse raves I've been to in the US but those warehouse raves had multiple household names. My biggest complaints: the heat, it gets INSANELY hot inside so bring a hand fan; the service at the bars, later on in the night service started to get a lot slower, it took 3-4 minutes to get a single bottle of water; the smell of cigarettes, it began to get extremely nauseating (though this is Europe, so I should have expected as much). Overall, Grelle Forelle was extremely fun and I believe I'll have to visit again before I leave.

I went to Vienna to visit a friend and he took me to Grelle Forelle to see a DJ set of Nina Kraviz. The venue was awesome, with triangular light structures hanging from the ceiling in an industrial space. That industrial style is perfect for Grelle Forelle's location, next to the river bank. Granted, for someone who is used to the prices of the Antwerp underground scene, Grelle Forelle was kind of expensive, but since I was on a holiday that didn't ruin my fun at all. What really took the party to the next level (besides the amazing Nina Kraviz obviously) were the laser lights. You can't find them any more in Belgian clubs and I'm a really big fan of laser shows. Thank you Vienna!

Pretty sick club, doesn't need to hide even by international standards. Loved the design of the club, very well thought out concepts and i think the best sound system in Vienna. Top quality bookings! And very quick and friendly bar-staff!
