Grelle Forelle

We attended an Isak Danielson concert here. It was a bit challenging to find the entrance, which is located down by the riverside. Contrary to several reviews I read beforehand, the staff was completely professional, and almost all of them spoke English. The venue itself was amazing, with a unique atmosphere and a distinctive interior. The sound quality of the concert was excellent, and the lighting complemented it perfectly. Perhaps the only downside was the expensive cloakroom, which cost €7.5. I will definitely return to this place.

Great music, great experience! THE best club in vienna if you are into techno (in my opinion). Not only the DJs are awesome there but also the clientele who goes there is super laid back and very open to meeting new people. I think Grelle Forelle will be my go-to for my time being here in vienna.

Normally the club is 21+, but today it seemed that every 16 year old kid was allowed in. We even heard the security guy asking the girl in front of us how old she was and she said 19, but because she had a ticket she was allowed in. It seemed like a kids birthday party in there. It was a terrible night and if it keeps happening like that I'm definitely not coming again and they should call themselves U4. Terrible, terrible experience.

Okay booking, decent sound system. Poor selection at the door and weird crowd (pushy, unfriendly people, more concerned with social media than with dancing). Usually too packed. No atmosphere Unfriendly/ unprofessional bouncers. Overpriced and overrated.

Ada at the club was amazing! She made our time there so enjoyable and friendly. Her presence and aura really added to the fun atmosphere. If you want a great experience, Ada is the one! she definitely deserves a big raise. 10/10
