Most of the pubs we have are now owned by large companies so they tend to be very similar inside. The branding of what they sell also makes them look the same.
I am no expert but I have noticed on holiday in Yorkshire that the quality of food in a few pubs is excellent. Recommendation is very important.
There are restaurants in America designed to look like this, to be quaint and gimmicky. Is this the real deal? Or does England suffer from the same sentimental commercialism?
