overview opening hours Coffee, cocktails, craft beer or brunch – you can enjoy all of these in the magnificent space of the Trade Fair Palace — from morning until night. Iconic armchairs, a clean, functionalist space and a great atmosphere at any time of day – that’s Kolektor. Although it’s the largest venue in Letná, it can fill to capacity — but there’s always room to sit on the stairs. Have you ever had brunch sitting on the stairs anywhere else? You can also visit the café bar on the first floor — the Atlas level, which is particularly popular with mums and children thanks to its fun kids’ corner with musical instruments. The space is also used to host events such as DJ sets or pop-up sales by local creators. opening hours january—december sun—tue 9:00—22:00 wed—sat 9:00—0:00 more about opening hours opening hours january—december sun—tue 9:00—22:00 wed—sat 9:00—0:00
