Standing on a sidewalk in the Richmond District of San Francisco at around six o’clock in the evening gives you a certain sense. Every thirty feet, the scents shift. Cantonese roast duck from one doorway, Burmese tea leaf salad from another, and then something distinctly Russian dill, sour cream, and beets drifting out of a bakery whose signage hasn’t been updated since the 1990s. It’s both crazy and amazing, which likely explains why a recent survey from the Escoffier culinary school named San Francisco the nation’s most diversified city in terms of cuisine, surpassing New York by a larger margin than most people would have predicted.
The study analyzed the diversity and distribution of 46 different world cuisines, then corrected for population and restaurant density. It used a system known as the Shannon Diversity Index to score 38 major American cities. San Francisco scored a perfect 100 to win. New York received a score of 92.58. At 91.69, Seattle secured third place. Coastal cities made up seven of the top 10. It’s the kind of discovery that, when presented clearly, begs the question, What is it about being near water that makes a city’s food better? Seafood is the simple solution, and it makes up a small portion of it. Who comes to a shore and what they bring with them is the deeper tale.
Here’s the table from the article:

Immigrant populations have traditionally made their first stops in American port cities, and they have always cooked. The oldest Chinatown in North America is in San Francisco. Vietnamese, Filipino, Japanese, and Ethiopian eateries can be found within a few pedestrian blocks in Seattle’s International District. These are the city itself, constructed meal by meal over many generations; they are not tourist attractions put on top of a metropolis.
The president and provost of Escoffier’s Boulder school, Kirk Bachmann, put it simply when he said that culinary diversity serves as an economic engine, generating jobs, attracting tourists, and providing locals with a cause. What’s more intriguing, though, is that population size isn’t the only factor in the correlation. With a population of about 650,000, Portland, Oregon, received a higher score than Philadelphia, a city that is almost twice as large. On paper, Seattle outperformed metro areas with much greater demographic diversity.
Bachmann pointed out that a flourishing culinary scene depends on much more than just demography, directly acknowledging this tension. These mid sized coastal communities are experiencing something different: a culture that values experimentation above pedigree, affordability for small businesses (at least in comparison to New York), and openness. An interesting story on the migration of West Coast chefs over the past ten years is presented. Peter Cho, who oversaw the kitchen at April Bloomfield’s The Breslin in Manhattan, relocated to Portland and founded Han Oak, where he began hosting Korean themed BBQ parties in his patio beneath a canvas tent with a hip hop soundtrack.
A concept like that might exist in New York, but it’s difficult to see it enduring there given the competition, rents, and pressure to be defined by a single, crisp concept. Cho was allowed to be strange in Portland, and it appears that the West Coast is known for its looseness. From Brooklyn’s Glasserie to Los Angeles, Sara Kramer and Sarah Hymanson took a similar jump, opening Kismet with a cuisine they called Turkish ish. In Los Angeles, no one gave a damn. The city’s natural tendency is to inquire about something’s flavor rather than its classification. Paradoxically, the cost of living has two functions. San Francisco, New York, Seattle, Boston, Washington, D.C., and many other highly ranked cities are costly.
This association was starkly noticed in the Escoffier study, implying that residents’ ability to pay for a varied culinary scene may have a role. That observation contains an unsettling truth. A client base willing to pay $14 for a lunch bowl is created by the same economic factors that drive out long term inhabitants. According to geographer Pascale Joassart Marcelli’s research in areas like San Diego’s City Heights neighborhood, the gentrification machine frequently starts with food farmers markets, pop ups, ethnic food festivals before real estate listings begin promoting culinary landscapes and home prices rise by 50% in three years.
It’s difficult to ignore the tension. Once the excitement attracts outside money, the very immigrant groups whose food makes a neighborhood lively are often the ones who can’t afford to stay. Even though a street vendor selling tamales from a cart may contribute more to a city’s culinary diversity than any well known chef, the vendor faces crackdowns while the chef is featured in a magazine. Despite their abundance of culinary offerings, coastal communities bear this paradox close to the surface.
Part of what makes the meal exceptional is the extreme inequity. The chain problem is another issue. Any big coastal city’s rebuilt downtown strip will have the same lineup of establishments, such as Salt & Straw, Sweetgreen, Blue Bottle, and Shake Shack, which began as tenacious independent companies before growing into something flatter and more standardized. Living in a neighborhood where you can see the In N Out from the Shake Shack and the Cold Stone from the Salt & Straw is how one Los Angeles writer described the phenomenon.
These chains aren’t all that bad. Some of them are truly excellent. However, by taking over premises that could have been occupied by a Salvadoran bakery or a Somali restaurant, they symbolize a form of convergence that goes against the variety these cities are praised for. Nevertheless, the experience on the ground supports the numbers, which don’t lie. The nation’s most intriguing, diverse, and unexpected meals are still produced in coastal cities. Yes, having access to fresh fish is important.
The histories of immigrants are increasingly significant. Most important is the culture of experimentation that flourishes in areas where the ocean is visible, where the continent’s edge seems to promote a certain openness. No one has yet to respond to the question of whether that openness can withstand growing rents and the increasing sameness of venture backed dining. For now, though, your greatest chances are still close to the ocean if you want to try anything new.
