Methodology Notes: For each subway perimeter, the most frequent cuisine type was identified*, the number of different cuisine types was calculated, as well as the total number of restaurants (subway restaurant density).
*Around 30% of the restaurant area classified as “American cuisine”, it is also the most frequent cuisine for a great number of subway’s perimeter. Additionally, there is an overgeneralized use of this class, since it includes incorrectly classified restaurants – e.g. steak and barbeque houses, fast-food, pizza, food courts, pubs, etc.). For this reason, and to better unveil the city’s cuisine diversity, this class was excluded for the determination of main cuisine type by subway and zip code, except for the case that there is no other cuisine type. UPDATE: the analysis for ALL classes can be seen on the subway 330ft limit area pop-up window, labeled as “cuisine_al”.
