“Love the rawness of this restaurant – it’s all about what makes Birmingham’s restaurant scene!” – You eat next to funkily graffitied walls, listening to a carefully curated playlist at Kray Tredwell’s well-known destination: “one of the city’s most interesting restaurants serving fine food prepared by a real, committed culinary artist”. Occupying Digbeth’s Custard Factory (and named after the birth weight of his premature daughter), “the extended restaurant is more spacious than previously and now has a comfortable bar area for preprandial drinks before guests are led upstairs to the main dining area where some of the tables still allow diners to watch the chef and his assistants prepare their dishes”. “Kray has altered the style of his menus several times in the past couple of years or so but has once more returned to serving a multi-course Tasting menu” and the result is “extremely well cooked and presented dishes” (“veering more towards being less eccentric and experimental than in the past and probably none the worse for that!”). Top Menu Tips – “the best barbecued Hispi cabbage ever, perfectly accurately cooked, glistening cod with smoked ham and delightful venison with maitake and a spot-on massaman sauce”.

For 34 years we've been curating reviews of the UK's most notable restaurant. In a typical year, diners submit over 50,000 reviews to create the most authoritative restaurant guide in the UK. Each year, the guide is re-written from scratch based on this survey (although for the 2021 edition, reviews are little changed from 2020 as no survey could run for that year).

What the Newspaper Critics are saying

The Guardian

Grace Dent thrilled to a “dark, daunting, uncompromising” but “never boring” venue in Digbeth’s Custard Factory development, from former Purnell’s and The Man Behind the Curtain chef Kray Treadwell – a place of “kitsch crypt décor” where a meal begins with drinks in a lobby that “feels a bit like being in an exclusive 1980s Soho hotel during a power cut”.

It’s not somewhere to go hungry, looking for meat and two veg, Grace advised. “Rather, it is very clearly a journey, an exploration, a culinary art exhibition or a high-concept dining experience… where chefs cook at a sublime level, but dish up such minuscule amounts.”

Over six or 12 courses, the menu is “a cascade of small, meaningful bowls, all of which just ooze flavour and, like all the best superheroes, turn up with an origin story.”
