Harden's survey result
Summary
“Unbelievably good food…”, “so clever…”, “each dish was perfection…”, “the best fish dishes I’ve eaten…”, “mind blowing!” – Tom Brown inspires superlatives with the “small yet superbly composed” creations as his “truly innovative seafood destination”. “The décor is industrial as you would expect in trendy Hackney Wick” and you can “sit at the counter and watch the chefs at work”. Service that’s “highly professional without being stuffy or offhand” completes an “unfailingly amazing” formula that’s currently one of the strongest all-round performances in town. Top Menu Tip – “signature crab crumpet is changed for winter by adding a rarebit on top”.
Summary
“Tom Brown is a genius with fish cooking” and his Scandi-chic venture with open kitchen in the hipster-central environs of Hackney Wick station provides dishes that are “exploding with flavour and full of originality (the sea bream tartare with miso-ponzu dressing and chilli oil was astonishing!)”. The place has “such a chilled vibe as well” – “it’s great to watch the open kitchen during service” and the atmosphere is “not in the least pretentious”, thanks to service that’s particularly “friendly and expert”. “My daughter and I went for her 21st and my 59th – amazing!”.
Summary
“In a rather unlikely location, tucked away around the corner from Hackney Wick station” – Tom Brown’s stellar yearling is one of the “most impressive” arrivals of the last year or so. His “super-fresh” fish dishes “are inventively conceived and perfectly executed” from an “original menu”; and served in an artfully “plain” and “relaxed” environment, which “brings the area’s industrial heritage to the fore, while injecting a hint of Scandi chic”. Staff are “very accommodating” too, and – with the open kitchen centre stage – “it’s lovely watching the chefs at work”. A few reporters consider it “a victim of hype”, but, for the overwhelming majority, it’s well “worth the expedition”.

For 32 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).

Cornerstone Restaurant Diner Reviews

"Nice food, but it would be nice to see more vegetables - the optional side, say, or a veggie starter. Atmosphere was nice, but service lacking- dishes coming out in the wrong order “you should have had this bread earlier” - staff not sure what the menu changes were for those with dietary requirements “I think it’s with cabbage” and sadly to say when starters came, one dish was delivered while the wait staff rubbed the back of their hand against their nose. We’re not disappointed we went but won’t be back. "

"Disappointing return after three years. Went back to try the venue out again. Started badly and went down hill in many ways. In my booking I specifically said I do not eat cooked cheese. The lady ( I later discovered was the manager apparently) made it clear that despite my advice, she was unwilling to alter the course, saying “it’s Parmesan and you will hardly taste it” I did and didn’t enjoy it! We did get one concession with another dessert not the cheesecake. The most concerning aspects were:- 1. A commis putting items onto a wooden skewer dropped something on the floor, used his gloved hands to pick the item up off the floor and whilst I didn’t see where that item went, he did not change this glove despite in clearly touching the floor. 2. Another chef doing some piping, initially got some on his fingers and licked it off, then carried on. The second time he went to lick his fingers again until he saw me looking so went to wash his hands. On two further occasions he glanced at me before deciding to wash his hands again. The lack of basic food hygiene concerns me. Whilst some dishes were delicious presentation has plummeted. The sharing plates are a significant loss from last time, how does one share one egg yolk between two people? Some other dishes were hard to “share” properly. We were served mainly by the female, who did most of the service in silence, little interaction, the male who served us a couple of the taster menu courses did it in total silence. Last time, I spoke to chef and told him his mentor Nathan, would have been proud of him. Today chef was having a day off and frankly this was not a great experience. Today took me to 106 Michelin stars, this experience sadly is in my bottom ten percent. Toilet clean but sign almost unreadable? Very saddened by this experience e mailed the restaurant with feedback but sadly no reply"

"A fantastic tasting menu with very friendly service. Food was of a very high standard and we will definitely return. Worth going out of your way for."
