Harden's survey result
Summary
“Located on the fifth floor of the Royal Opera House” – this amenity for opera-goers is also open to the public throughout the week, and for the heart of Covent Garden its appeal for many probably lies in the general absence of hoi polloi from these cultured environs. Its top feature is a bright, glazed terrace with fine views over the area, which comes into its own in summer. Fans rave over its brasserie fare too (for example “excellent steak”), although they generally opt for the “well-priced set lunch menu”; critics say you get “rather small portions of OK food at high prices”.
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).

Royal Opera House, Piazza Cafe Restaurant Diner Reviews

"When visiting the Opera House this is the perfect place to book to dine as you have access to the table for the whole evening and can enjoy your meal spread across the performance - e.g. dessert & coffee in the interval. Food has improved immeasurably since the Opera House brought the cooking in house and while not cheap is pretty good value."

"The perfect addition to a night at the opera where one can have access to your table for the whole evening. This means that one can spread the course over any intervals - e.g. having dessert and coffee in the interval after starters and mains pre-performance. Since the opera house brought the food preparation in house quality has definitely risen and the value improved."
