With this restaurant you always feel the need to come back and try it again. With the loveliest food and service from the family run restaurant, you will get the best service available and then some more. Beer is top class in Ninh Binh and the food is also the best. All vegetables are grown by themselves and the meat is purchased daily and almost nothing comes frozen.

Prices are easily visible on the menu and even if they don't speak lots of English they will try their best to get the best food possible just for you.
Owner does speak some German which might help, otherwise it's mostly handsignals and trying some Vietnamese!
