Chain restaurants such as the Berni Inns, created by Italian brothers, Frank & Aldo Berni, began to appear in every British town and city in the late 1960’s and early 1970’s. They served the classic favourites of the time; Melon or Prawn Cocktail to start, followed by Mixed Grill or Steak, and Black Forest Gateau or Lemon Meringue Pie to finish. Quality of ingredients was high, with beef being flown in from Argentina, way before Gaucho’s made a name for themselves!
These type of establishments had a pub-like atmosphere and were often ‘themed’ with rural or sporting decor.
Brewery owned pubs now joined in the boom in eating out as they realised that was profit to be made in food as well as drink.
Here’s a short clip about the birth of the Berni Inn, the very first steakhouse chain to appear on Britain’s high streets. http://www.bbc.co.uk/programmes/p02l4ghm
