The following photo contains two important words in Vietnamese .These two words also quite useful for any western tourist travels to Vietnam .
Com : This is actually sound like "kerm" and not relates to anything about computer at all .
The 'com" here just means "cooked rice". The main staple food for many Asian communities.
Ga: (i have no Vietnamese input so this word show just Ga here) Ga means Chicken .
So "com ga" = rice chicken which means "chicken rice" in English . The teriyaki is the adopted japanese word which we already understand the meaning.
One thing... Do not confuse with "Ca" which means "fish"Be careful ....haha
