Lots of red lighting, red leather upholstery and air-brushed flames on the walls characterise the design of this industrial club space, which has a great set-up with plenty of places to sit and relax or observe the large dance-floor - presided over by the towering DJ booth - a half level down. While the arrangement would be ideal for gladiator-style battles, Kotłownia is mostly full of young kids awkwardly finding their groove for the first time. If your student ID has expired, you'd be wise to head elsewhere; however if you're underage in your home country and looking for a teen dance party in Gdynia, well this is your jackpot. It was Thursday when we dropped in, so note that the opening hours vary to some degree with events.
