If you're looking for something unique, give it a whirl!
As…read morelong as you understand that it's basically an imaginative cocktail bar with lovely servers, you won't be disappointed by the 3 dimensions hype. You don't go into different rooms, there's just one bar and they change the lighting to signal the next dimension. There's a different menu for each dimension, which initially seemed like a ploy to get you to order more, but I think they've just missed some kind of detail somewhere that would better pull it all together. Regardless, it was memorable, the drinks were fun and unique, and our bartender was delightful. (If the owner is reading this, I don't recall his name, but he used to play hockey!;)
We rang the doorbell and a peculiar fellow poked his head out...we went inside and he told us the story and offered to take our coats before we went up and into the bar. I wondered what we'd gotten ourselves into at that point, but carried on. The interior was awesome and my eyes devoured it all, never short of something new to explore. We sat at the bar and had a few drinks and some good conversation.
It's kind of kitty corner to the Barcelo hotel.
