Time Out says
This small, red-brick basement bar is decked out in wry, kitsch-but-cool details, with a veritable solar system of tiny mirrorballs hovering above the bar, and a seating area that – illuminated by tiny pinpricks of light emerging from bronzey-yellow panels – looks like the inside of a huge honeycomb. During the day Kolaž serves coffee to local office workers and lawyers, while by night it fills up with a sophisticated bohemian set with an easy-going straight-gay-whatever sense of social orientation. The music ventures into similar areas of ambiguity, ranging from PJ Harvey to La Roux with all kinds of indie-rock, synthi-pop, electro-disco and exotica thrown into the mix. Czech-brewed Vévoda is among the bottled beers, while the handsome array of spirits includes some fine local liquors – ruta (rue brandy) being a particular one-more-for-the-road favourite. Weekend nights can be a tight squeeze.
