I love Xi an cuisine so have been meaning to try Xi'an Biangbiang so I could compare it to other ones I have tried in London.
As well as Central London, there is another branch at Aldgate East but as I was near Covent Gardens and checking out this other eatery nearby, I dined here.
I had the Skin cold noodles in Traditional sauce (liangpi) and Pork and veg Wontons in chicken broth.
The liangpi was nice in all respect if they get the vinegar, chilli ratio correct but I felt that the noodles were just Cantonese flat rice noodles.
Although, they had that chew like Liangpi, the width was not as wide or as thin as the liangpi I have tried at other restaurants.
The wontons were just the usual pork wontons, nothing exciting but the seaweed and shrimp was on the stingy side if you refer to the picture on the menu.
I found the wontons a bit boring so dunked them in the remaining liangpi dressing and vinegar.
According to the staff, Dong hu old vinegar is a nice vinegar from Xi an.
Overall, not bad and the staff were really nice.
