The place looks fantastic, and as one of the few places in Swansea that primarily serves cocktails, they certainly deliver one of the best experiences.
A group of 10 of us went here for a celebration, and although it was great to share a few cocktails amongst friends in an aesthetically pleasing locale, we all found it incredibly hard to talk because of the blaring music. It's not a large place, so the music just fills the room, drowning any attempt at chatting.
The noise level was on par with a club, rather than a bar. I'd recommend the owners turn the music down a notch or two. Other than that, it's worth checking out for the drinks alone.
