Although most San Diegans would say tacos are the region’s most popular food, a recent national study ranked San Diego only eighth on its taco passion list. The list’s top 10 cities are: Austin, followed by San Jose, San Antonio, Oklahoma City, Los Angeles, Las Vegas, Houston, San Diego, Phoenix and Riverside. According to the data-driven study published by Clever Real Estate on Sept. 29, San Diego fell far behind seven other cities based on the percentage of revenue each city’s restaurants chalked up to taco sales, among many other factors.
