Tyler Cowen’s Ethnic Dining Guide for the DC area has been updated for 2009. He starts off with a plug for his book, Discover Your Inner Economist, offers some rules of thumb for choosing ethnic food restaurants in general, lists some “must-eat” places, then launches into a grand, culturally-alphabetized list of restaurants of every regional and stylistic variety, with addresses and capsule reviews. The guide is huge and tirelessly comprehensive, definitely worth a scan if you’re hankering for an exotic dine-out this weekend.
