Thanks to a tip from Marty L., I had a terrific experience at Daruma, a Japanese market in Bethesda that serves lunch and dinner up until 7 or 8pm at a little counter. The kind of place every Chowhound should know about. I love the guy who brings out the food. They offer a few soups (mostly a choice of which kind of noodle you'd like), snacks, and some rice dishes. Go check it out if you're in the hood! How I wish I had a place like this near me.
