I was in this bar with my girlfriend, we ordered whiskey coke and Long Island. In both drinks the coke was not sparkling, Asked to change the drinks in a very polite way, and were not heard! On our insistance the staff reacted aggressively like "you don't like this coke because it's vietnamese!" and nearly threw it to my face,
I still cannot believe how they can react like this because of a stupid usual bar mistake to use a can of coke opened long time ago. They could easily try it and make another one and we paid already so we were very disappointed.
stupid impolite aggressive will never go again ever (and i live in Nha Trang)
