Cornwall Services has been crowned king of the Big Macs as the highest rated McDonald’s in the UK, according to data from Google reviews.

The new study has revealed the highest-rated McDonald’s in the UK, with Cornwall Services crowned top.

The research, conducted by QR Code Generator, looked at the percentage of five-star and one-star Google reviews for all McDonald’s across the UK to see which were the highest-rated and which were the lowest-rated.

Cornwall Services in St Austell, Cornwall, has the highest-rated McDonald’s in the UK. The fast-food outlet recorded 52.42% of users leaving five-star reviews, compared to just 6.18% of users leaving one-star reviews, and has a rating of 4.1.

Typical of the reviewers on Google was Skater Bun who said: “One of the best McDonald’s I’ve visited and we do get around as a family.

“We always visit Cornwall services MD as the atmosphere is lovely, the restaurant is bright airy and clean and we can always find somewhere to sit. The staff are helpful and diligent and food arrives reasonably quick.”

Following in second is Omagh in Northern Ireland, with 52.26% of reviews being five stars. Only 8.70% of users left one-star reviews at this McDonald’s franchise, and it recorded a Google rating of 4.1.

Coleraine in County Londonderry ranks as the third highest-rated McDonald’s in the UK. The franchise recorded 51.32% of reviews being five stars and a Google rating of 4.1. This restaurant has also received a low number of one-star reviews, at just 7.58%.

At the other end of the scale, Chingford has the lowest-rated McDonald’s in the UK, with 36.49% of reviews being one-star. Only 24.07% of reviews left gave the outlet five stars, and it has a Google rating of 2.8. 

Sydenham is the second lowest-rated McDonald’s in the UK, with one-star reviews accounting for 34.05% of all reviews, while Bristol Fishponds is placed third, with 33.46% of reviews being one-star. 

Commenting on the findings, Marc Porcar, CEO of QR Code Generator said:  “Exploring which McDonald's in the UK is the highest-rated and lowest-rated can be interesting as it can provide a snapshot of customer satisfaction.  

“McDonald's is known for its standardised operations, yet there can be variability in how well these standards are implemented. Seeing which outlets are highest or lowest-rated can highlight the strengths and weaknesses of the company's efforts to maintain consistency across all its locations. 

“The ratings might reveal differences in consumer expectations or experiences across various regions. For example, a McDonald's in a tourist-heavy area might have different standards or challenges than one in a rural town. This can lead to discussions on how location impacts service quality.”
