The surprising economics of sushi

A Netflix documentary ignited an omakase sushi craze

Before 2012, edomae omakase was an expensive sushi experience that was not particularly popular in the US. That changed with “Jiro Dreams of Sushi,” a 2011 film about the 85-year-old owner of Sukiyabashi Jiro, an omakase restaurant with three Michelin stars, that earned rave reviews. Demand for omakase exploded, and restaurants responded by raising their prices.

'Omakase' roughly translates to 'I'll leave it up to you'

An omakase restaurant allows sushi chefs to craft custom-made rolls for patrons. The meals are often expensive, but there are good reasons for that: They include the freshest ingredients the restaurant has to offer and usually have limited spots. This short documentary focuses on Royal Sushi and Izakaya in Philadelphia.

One writer suggests using the California roll to evaluate sushi restaurants

Christine Carone uses the logic of the Big Mac Index—a metric for evaluating purchasing power by comparing countries’ Big Mac prices proposed by the Economist—for evaluating takeout sushi. Her recommendation is looking at the cost of a California roll, a relatively inexpensive, middle-of-the-road item for any American sushi spot. If it’s too expensive, the restaurant isn’t offering good value. But if it’s too cheap, you should worry about the quality of the fish.

Norway is responsible for salmon sushi

Japanese sushi did not include salmon until the mid-1990s because Pacific salmon was known to contain parasites. Norway, meanwhile, had an abundance of Atlantic salmon, which was safe to eat raw.
