Easily one of the coolest and different cocktail bars I've visited, everything about this place was great, sort of muesuem like with taxidermy animals, the fake dinosaur/ whale thing on the roof was cool, even the menus are Super unique and interesting.
Great friendly service, good recommendations, really tasty and unique drinks.
If you're only going to visit one cocktail bar in Hanoi this should definitely be it,.
