Kumquat Tree Speakeasy is a hidden cocktail bar in To Ngoc Van, Tay Ho, Hanoi. The menu includes original drinks such as Dita Khoi with pandan and coconut, and Hoa Nhai with strawberry aroma and soda, and cocktails can be adjusted to order. Pressing the bell at the entrance opens a secret door and leads upstairs. Music is louder than expected even if you anticipate it to be quiet.
