"Xi’an Impression is London’s outstanding Xi’an Chinese restaurant and chef-owner Wei Guirong’s small, unassuming restaurant is a specialist in hand-pulled noodles. The most famous are “biang biang” (so called for the noise they make when being stretched and hit against a work surface): Long ribbons of dough noodles arrive coated in a deep, earthy seasoning, with blanched Shanghai bok choy; garnished with hot oil, chopped garlic, spring onions, and ground chilli." - Adam Coghlan
