Well I live in London where food was invented so….
Fried fish is a Jewish import from Europe, and became popular in London's East End, which had a strong Jewish community. It's likely the custom of eating Fish and Chips originated in this area. Other Jewish foods, such as Pickled Herring, Bagels, Latkes and Salt Beef became local delicacies.
I've never eaten Jellied Eels, but I do like cockles and mussels, which were traditional 'poor man's food' here.
The London Docks saw many spices and exotic foods coming in from all over the World. Many sailors settled here, and brought their culinary customs with them. You had Chinatown in Limehouse, and then those fromBritish India. Today's curry centres of Brick Lane and Green St are testament to that immigration.
Now, we have Polish, Lebanese, Ethiopian, Turkish, Caribbean and all sorts of other eateries. Fabulous. You can still get a bloody good fry-up too.
India Pale Ale was first brewed here too.
