Greek Restaurants in London: Souvlaki in City. London is one of the most ethnically diverse cities in the entire world, making it a hotspot for some of the best cuisines on earth. London is a foodie paradise, an Eden for immigrants. Following World War II, large numbers of Greek-speaking immigrants moved to London, settling all over the city. In addition to their language and culture, these new settlers brought along their delicious cuisine, quickly making the newly established Greek restaurants in London enormously popular. These small Greek eateries became beloved not only by the immigrant community, but also amongst city dwellers across the ethnic spectrum, allowing London Greek restaurants to thrive.
