Kangakoi Whiskey

I believe there may be a slight confusion in the name of the food you are referring to. There is no food named "kangakoi whiskey" found in restaurants in the USA. However, there is a type of Japanese noodle dish called "Kangkong Guisado" that is sometimes served in Asian fusion restaurants. It is possible that this dish is being mistaken for "kangakoi whiskey."

Kangkong Guisado is traditionally made with water spinach (also known as kangkong) that is stir-fried with garlic, soy sauce, and chili peppers. It is not a noodle dish that is typically served with whiskey.

If you are referring to a different dish or a specific restaurant's menu item, I would be happy to help you with more information. However, based on the information provided, I cannot find any evidence of a dish called "kangakoi whiskey" being served in restaurants in the USA.
