Et Voila - Tim and I found out about this place because they served amazing waffles at the Belgian ambassador's national day party (yes, we are fancy). They are in the Palisades area of DC, and thus only accessible by car or taxi, but there's a huge upside: if you make reservations after 9:30pm, you get a free bottle of wine. Good Spanish wine, too! I had veal sweetbreads (a guilty pleasure of mine) and curry-flavored moules frites. Tim had smoked trout which he loved, and stoofvlees which he loved a bit less.
Bistrot Le Zinc - this place is located on Wisconsin Ave. north of Glover Park, about 20 min walk from where we live. It's only been open for a few weeks but we were really impressed with both the food and the service. I had a tasty hot goat cheese salad and red snapper with an eggplant tapenade, which was really strong tasting but good. Tim had a sea scallop appetizer and giant delicious leg of lamb for his main course, and we split a chocolate cake for dessert. We want to become regulars here, we liked it so much.
