CityZen - best restaurant in DC
The Source - best newcomer, real potential, currently my #2
Eve - in Old Town Alexandria, outstanding
Maestro - closed, will wait to see what a new chef can do
2941 - waiting to see what the new chef can do
Citronelle - I don't care what anyone says, too inconsistent for what you pay, not as if Michel Richard is cooking for you every night
Central - Richard's other place in town, good, overpriced for what it is and it's supposed to be a value
Minibar - the most interesting meal in DC, our version of El Bulli, but you only go once every few years.
Tosca - consistent upscale Italian, not amazing, but my favorite place for Restaurant Week
PS7 - need to try it again, 6 months ago was really outstanding
Farrah Olivia - very good for Alexandria (Alexandria's second best)
Black Salt - other people like this place, I don't get it
Vidalia - once great, then terrible, now 'good'
Hook - I wasn't impressed, but many are, good 'for Georgetown' - likely to be terrible in a year
Willow - don't make a trip, good for Ballston, worth eating here if you're staying at the Westin Arlington
DC Coast - consistent food, busy, not great service
For a latin flavor I still like Oyamel and Ceiba. For a bit more downscale French comfort food, Bistrot Lafayette in Old Town. (And Cafe du Parc at the Willard makes for a nice Sunday brunch during the time of year when you can eat outside, but then if you're going for a nice spot rather than the food it's worth going to Indigo Landing near DCA... closed until summer... food isn't good but it's a wonderful location).
DC does Vietnamese (anything in the Eden Center!) and Thai (Dungrats, several on Van Dorn in South Alexandria, and there's a newer, nicer place in Fairfax that's supposed to be good I haven't tried yet).
Oh, and give Nora's a miss. Last time I was there they brought me my duck well done, and argued with me when I objected ("That's how duck is prepared in DC.")
