I've found a local list of restaurants that might help. You can narrow down the Washington results by cities close to you. If you phone several of the restaurants you can narrow down wich one would work best for you. http://www.restaurantreviewsratings.com/鈥?/a>

Ok, if you go to the Adams Morgan neighborhood you are sure to find a few. I would also stop at Julia's Empanadas when you get a minute (not tacos though, sorry).
