I will have to question some of the cities we fell behind, specifically Houston and New Orleans mainly because there is a lack of culinary variety in these cities. Also southern "comfort food" has it's limits.
What also makes our ranking spectacular is that DC is a small city in comparison to all the others. For example DC has a population of 601,723 making it the 27th largest city where as New York, Los Angeles and Chicago rank 1,2 and 3 respectively in terms of population all boasting at least 2.8 million people. So on a per capita basis we must rank in the top 5.
Some notable honors for DC, we have the countries best Spanish and Indian restaurants and a hand-full of great Italian restaurants. The future will only look brighter as this is a city that is growing in terms of both population and jobs. The growth in population is concentrated mainly in young highly educated professions that have a demand for sophisticated fine dining.
