Food and Economics
One of my favorite ways of telling that a link or idea is really worthwhile is that I find myself mentioning it fairly frequently after reading it. This has happened with Tyler Cowen’s Ethnic Dining Guide entry “General Remarks” where he goes over the basics of what makes a good ethnic restaurant. It includes simple economic rationales for how to choose the best ethnic dining like, “The best ethnic restaurants are often found in suburban strip malls, where rents are lower and the degree of feasible experimentation is greater. Small and cheap ethnic restaurants are often better than large ones.” It’s worth a read wherever you live (but especially if you’re in DC which is where it’s focused).
(Also on the food and economics tip, Paul Krugman and Stephen Dubner explore why food isn’t so good in the UK.)

Hi, I'm 
The dining guide is focused on DC, not New York.
Oops, fixing that now. Sorry.
I saw a news item about this on TV last night. Thanks for covering it in greater depth
