WalletHub, the statistical aggregating firm that compares quality of life in cities and states, ranked 150 cities in affordability of restaurants as well as diversity, accessibility, and quality of them. San Diego doesn't do well. It's 68th in affordability of dining and 89th in diversity, accessibility, and quality.
In rating affordability, WalletHub looked at average beer and wine and groceries costs; prevalence of affordable restaurants with 4- and 5-star ratings, and sales taxes. In diversity, accessibility, and quality of dining, the statisticians looked at the number of restaurants per capita; ratio of full-service restaurants to fast-food establishments; access to healthy food options; number of farmers markets; number of craft breweries and wineries; number of coffee and tea shops per capita; number of gourmet specialty stores per capita; number of grocery stores per capita, and number of food festivals per capita.
Most affordable dining was in Austin, Texas. Number one in diversity, accessibility, and quality of the food experience was San Francisco, which also had the highest number of restaurants per capita. That is hardly surprising. The city that did the best in both categories was Orlando, Florida. Lowest number of restaurants per capita: Bakersfield.
