Victor Babenko Review from Google
3.0★
Victor Babenko's Review Sourced from Google
This would’ve been an amazing venue if there was any ventilation at all, and the entire space wasn’t instantly getting full of smoke from the smoking area. The amount or second hand smoke you’re getting here is insane. Ventilation here is basically “let’s just keep the doors open and get all the smoke back in”.

The place is spacious. Get to the bathroom early as it is unisex and there are only three. The art displays are super cool with an interactive French one covering a wall and another heat sensitive one that is like the exploratorium.

Had a really nice evening with some favorite music played. In a different way than I had experienced before, but it was a unique experience overall and one I would certainly consider again in the future. The skill level of the quartet was top notch and together they really produced a rich and magical performance, enhanced by the candlelight that illuminated the stage. It only lasted an hour, but that was enough to fit a lot of crowd-pleasing songs from both ABBA and Queen.
