This restaurant is listed in the 1000 Places To See Before You Die book and is also listed in my Frommer's Vietnam Guide book as a place to go to when in Hanoi for a meal. I think it is time for this restaurant to be de-listed. Yes, it is unusual go to a restaurant that serves only one dish. But, I did not find the one dish that fantastic. This coupled with a less than appealing environment of poor service, questionable hygiene, and lousy decor makes me give this restaurant only 2 stars.
By the way, even finding this restaurant is difficult. There is a restaurant across the street with a bigger sign with the same name. If you really want to go to the original restaurant, make sure you look for the number 14 street number.
