Which cuisine are you most likely to be satisfied with when dining out? Which disappoints you the least # of visits?
Cowen---an economist, New York Times columnist, professor, and writer of "Tyler Cowen's Ethnic Food Guide"---answers on his blog:
Korean is perhaps the safest bet, for two reasons. First, non-Koreans are not usually interested in the food. They might enjoy Bul-Gogi but there will be plenty of other dishes for Korean patrons and these will not be "dumbed down." The lack of mainstream interest limits the potential for sell-out behavior on the part of the restaurant. Second, many Korean dishes, most of all the pickled vegetables, "travel" relatively well and do fine in a culture -- the USA -- which is not obsessed with fresh ingredients.
The most dangerous cuisine to try, in the United States at least, is Chinese.
