A little over a month ago, when I linked to my blog post on Red Egg on Facebook, I made a half-serious joke about how should I have a “dim sum bracket” akin to Nate Silver’s “Burrito Bracket” on his FiveThirtyEight site. The burrito bracket, as Silver explains, was born out of his love of burritos and his then-recent 2007 move to the Wicker Park neighborhood of Chicago. He then started a food blog to document his search the best burrito in the neighborhood, NCAA March Madness style. However, his work for Baseball Prospectus and start of what would become FiveThirtyEight deferred his search in the middle of the bracket.
I was really captivated by Silver’s relaunch of the Burrito Bracket as a nationwide search to find out what was the “best” burrito in the country. Thus, I decided to actually launch my half-serious joke into a project to find the restaurant that serves the “best” dim sum in the country (and when I mean dim sum, I mean the Cantonese style food and not others that may market itself as dim sum).
Of course, I don’t have Silver’s access to staff journalists, researchers, or a veritable selection committee of food journalists and celebrity chefs. However, I did have access to public access to crowd sourcing restaurant review sites, Chowhound discussion forums, and the online publications of numerous rankings of dim sum from various metropolitan areas. So I started similar to how Silver started his revived Burrito Bracket – Yelp.
Yelp scores and numbers of reviews may be a decent baseline, but even Silver himself acknowledges the potential flaws in Yelp. Renown Chinese food eater David Chan goes even further to describe the flaws of Yelp when searching for Chinese restaurants. Thus, I decided factor in other websites in creating my rankings, most notably Urbanspoon. Urbanspoon isn’t without its own flaws, but its another crowd sourcing restaurant view site used nationwide and I thought it would help balance some of the downsides of using Yelp. In addition, I factored in “bonus points” for the number of times a restaurant had been ranked as part of a list of best dim sum places in a metropolitan areas in the last two years by a food journalist and/or Chowhound. No ranking system is perfect, of course, but I thought that might be the best way in having a relatively objective rating system.
Critiques of the rating system (and scores for that matter) will be saved for another post, however, as I want to talk about some initial findings that I think are pretty fascinating in their own right.
In my search for the restaurant serving the best dim sum in America, I did a lot of scouring to find all these restaurants. All in all, I found at least 494 restaurants serving dim sum across 57 of the largest metropolitan areas in the United States. I got to 57 by searching for dim sum restaurants in both the 50 largest cities in America and the 50 largest metropolitan areas as defined by the Census Bureau. Honolulu falls below 50 in both categories, but has a significant population of those identifying as a person with Chinese descent so I included it too. In total, these metro areas account for 85% of all American residents that identify as Chinese in the 2010 census.
Afterward, I was curious to see the correlation between the amount of Chinese identified Americans in a metropolitan area and the amount of restaurants in the metropolitan area that serves dim sum. As you might think would be fairly logical, in general there is a pretty big correlation between the two. Using rudimentary and free statistics software by the website Alcula (as I don’t have access to SPSS, STATA, or other more sophisticated software), I found that the correlation coefficient between the two is pretty dramatic at 0.946 as you can see from the scatter plot above.
While that doesn’t come as much of a surprise, I was interested to see which metropolitan areas matched closest to the regression line and which were significant outliers. The two metropolitan areas that looked most in line were Washington, DC, at 13 restaurants serving dim sum in a population with 106,721 Chinese people, and Dallas-Fort Worth, at 8 restaurants serving dim sum in a population with 55,568 Chinese people. Beyond those two metropolitan areas, I would say a vast majority of the other metropolitan areas were pretty close to the region with just a few major outliers.
The few outliers, however, were pretty significant. The most significant outliers, in fact, looked to have a lot MORE restaurants serving dim sum than their Chinese population would otherwise suggest. The two biggest in this case were the San Francisco Bay Area, with 72 restaurants serving dim sum in an area with just 649,496 Chinese people, and Seattle, with 33 restaurants serving dim sum for an area with just 100,763 Chinese people. This can be explained by the fact that both cities retain significant numbers of people with ancestry from Guangdong Province and/or ties to Hong Kong. Furthermore, both cities not only retain a significant and vibrant Chinatown filled with Cantonese families, unlike their counterparts in places like Los Angeles or Washington, DC, but they also have suburban areas with a significant number of Cantonese families are restaurants, like Bellevue in Seattle and Millbrae in San Francisco.
In contrast to San Francisco and Seattle is New York City, which has only 53 restaurants serving dim sum in the metropolitan area that is home to 705,721 Chinese people. This can also be explained by Chinese immigration patterns as the predominant majority of Chinese people that have immigrated to New York since the Immigration Act of 1965 have been from non-Cantonese areas of China, especially from Fujian, Taiwan, and Zhejiang. While the core of what most people see as Manhattan’s Chinatown is still predominantly Cantonese, it is dwarfed by Flushing’s much more diverse pan-Chinese Chinatown and is even smaller in land area than the Fujianese side of Manhattan Chinatown, just east of Bowery and along East Broadway.
Sacramento and San Diego also have less places serving dim sum as their Chinese populations would indicate. As a native San Diegan, my theory is that many Chinese families are willing to drive a couple hours to San Francisco and Los Angeles, respectively, for their fix of really good dim sum on any given three day weekend.
Regardless, I feel the best finding in all my research is that in nearly every major metropolitan area of the United States, you won’t be far from a place that serves dim sum, most of them at least decent. Even in Albuquerque, with just a few thousand Chinese people, I’m never really more than a 20 minute drive from eating dim sum at Ming Dynasty.
