Why are American restaurants popular in Glasgow?. Glaswegians have always looked across the Atlantic for a bit of cultural inspiration. Perhaps it comes from the city's history as a port with close links to America, or perhaps it's the locals' traditional fondness for country and western music. Now, though, Glasgow's American restaurants are taking the city by storm. The food of the US has developed hugely in recent years, from the burger bars we are familiar with to a much more diverse cuisine. America is a huge country and this is reflected in the extraordinary variety of dishes now being served in American restaurants in Glasgow.
