Ruby's was just opened by K Bar's Adeline (and her cool dude Rasmus) a few weeks ago, so you won't find anything online and they will never do any promotion (they don't need to)

Ruby's is located in Nybrogade, a tranquil canal right off the main strip and 2 min's walk from both Torget and Kongens Nytorv, where you'll most likely end up if you ever visit København. The bar is in, and feels like, somebody's appartment. Tall ceilings and windows, old cornecing and comfy sofas are mixed with modern furniture, red velvets and other contrasting materials.

My favourite bits
1/the raunchiest and rudest moments of RAW are playing on a loop in the loo; watch people coming back to their seats laughing their heads off. Unique.
2/ indoor garden with heaters and cobbles where on can smoke in peace
