Well, Cuban STYLE food is quite good but currently unavailable in Cuba because of the Castro Bros.. Okay, I am more referring to style of cooking than availability. So while little food is available in North Korea, Korean food in general can be quite tasty (and also available in South Korea).
The woman who owns it is Cuban but I don't know if she is actually from Cuba or is American. Also I don't know if the food is traditional Cuban food. I will ask next time I go there.
