Customers have voted Byron and Browns as the two eating-out brands that leave them most satisfied, while Five Guys topped the poll for quality of food.
That's according to CGA Peach's BrandTrack survey, which asked a range of questions to try and highlight the nation's top 40 best-performing brands.
In addition to Byron and Mitchells and Butlers' Browns brand, who were joint leaders of BrandTrack's overall satisfaction ratings, buffet brand Cosmo, Wagamama and Green King's Loch Fyne rounded out the top five.
Other findings included:
- Five Guys was ranked highest for food quality, with 53% of customers "very satisfied". Loch Fyne was second with 49% and Wagamama was third with 47%.
- Crown Carveries was rated highest for value for money with 45% of its customers giving it top marks, ahead of Cosmo at 42% and Toby at 40%.
- Jamie Oliver's Jamie's Italian topped the list of satisfaction with service, with 43% of its guests strongly agreeing it was good. Browns was at 42% and TGI Friday's at 41%.
- Patisserie Valerie was the top-rated brand in the cafe, fast food and bakery sectors, with 39% of guests very satisfied with their experience.
- Other brands rising quickly up the overall customer satisfaction chart in 2015 included TGI Friday's, Bella Italia and Cafe Rouge.
Peter Martin, vice-president of CGA Peach, said: "The UK's eating-out market is more competitive than it has ever been, and all brands have to work incredibly hard to keep their guests satisfied. These fascinating figures reveal which of them do so best, and we salute them all."
All satisfaction ratings were based on CGA Peach's BrandTrack October 2014 survey of 5,000 British adults who eat out.
