Master Wei Xi'An
Biang biang is the sound of the dough hitting the bench, and Guirong Wei has been making those noodles in one small Bloomsbury room since 2019.
Why go
Guirong Wei co-founded Xi'an Impression in Highbury, then opened this on Cosmo Place, a lane behind Southampton Row, and it won the Observer Food Monthly Best Newcomer award in 2019 (Master Wei). Shaanxi cooking is its own thing and the room treats it that way: hand-stretched biang biang noodles, cold-skin liangpi under chilli oil, cumin-heavy beef in a flatbread. The Infatuation's Heidi Lauth Beasley scored it 9.0 in September 2024 and said the beef biang biang are the best in London2. Seven months later Yotam Ottolenghi named it in the Evening Standard as the place he sends people to eat alone. The room is small, plain, and has a couple of beers on tap.
Order this / avoid
- Order: the beef biang biang noodles first. Then the Xi'an liangpi in the traditional sauce, which Beasley says words cannot do justice to. Smacked cucumber for the table. The spicy cumin beef burger, which she rates above the stewed pork version.
- Avoid: the steamed pork and vegetable dumplings, which is the one thing she marks down:
You'll find better steamed dumplings in London
2. And do not count on walking in at peak.
What locals & experts say
- Yotam Ottolenghi, in the Evening Standard (24 April 2025), on his own list of where he eats:
I'm not sure how much of a secret it is any more, but Master Wei. Guirong Wei is a Xi'an noodle specialist who has brought authentic Xi'an food, with its rich 2,000-year history, to the UK. It's the sort of place to fly solo. A laid-back spot where you can slurp away, accompanied by a newspaper or headphones.
1 - Heidi Lauth Beasley, The Infatuation London (11 September 2024), 9.0 out of 10:
sitting down at Master Wei, knowing that you've made it back for another bowl of London's best beef biang biang noodles is a feeling you'll go out of your way to recreate.
Her caveat is in the same piece, on the dumplings.2 - Grace Dent reviewed it for the Guardian under the headline
Master Wei, London WC1: An assertive culinary hug
. The Guardian URL would not resolve on three attempts, so that headline is reproduced here from the restaurant's own press page and Dent is not tagged as an endorser until the primary link is found.3 - Observer Food Monthly Awards 2019, Best newcomer, also recorded from the venue's press page rather than from the OFM itself.
Good to know
- Where: 13 Cosmo Place WC1N 3AP, a short lane between Southampton Row and Queen Square, five minutes from the British Museum. Holborn or Russell Square tube.
- Which one: there is now a second Master Wei at Bechtel House, 245 Hammersmith Road W6. This entry is Cosmo Place, and every source above predates the Hammersmith opening.
- Sister restaurant: Xi'an Impression in Highbury, which the same chef co-owns.
- Booking: worth it. The room is small.
- Price: cheap for the cooking. Beasley's line is that it is affordable enough to be a habit.
- Hygiene: the FSA records rating 5, inspected 28 May 2025, with components 5, 5 and 5, where lower is better.4
- Michelin: not recorded either way. Our cached Michelin data is stars only, so its silence means nothing about guide selection.
Verdict
must-visit — Biang biang is onomatopoeia. It is the noise the dough makes hitting the bench as Guirong Wei stretches and slaps it flat, and she has been making those noodles in a small Bloomsbury room since 2019, having already co-founded Xi'an Impression up in Highbury. The Observer Food Monthly named it Best Newcomer that year and Grace Dent went in for the Guardian. What settles it is two independent voices since. Heidi Lauth Beasley scored it 9.0 for The Infatuation in September 2024 and called the beef biang biang the best in London, and Yotam Ottolenghi named it in the Evening Standard the following April as his London secret and the place to eat alone. Order the liangpi, cold skin noodles under chilli oil, and the smacked cucumber, and the cumin beef burger rather than the stewed pork one. Skip the steamed dumplings, which is Beasley's own caveat. It costs very little, it is one small room, and Shaanxi cooking done this well by the person who introduced it here is not something you can substitute.
