I love Thai X-ing (DC), Meaza (Baileys Crossroad), Nava Thai (Wheaton), Hong Kong Palace (Falls Church), China Star (Fairfax), Bombay Indian (Silver Spring) and Angeethi (Herndon), plus just about everything Vietnamese in Eden Center (Falls Church). The 9th Street Ethiopian row is very good as well, and also Zenenbech, up on Florida/U/5th or so. Those places are very good and I can eat at them more or less without limit. There aren't many places around as good as those.Much more after the link.
