A crowd of Eastern European expats frequents this red-splashed Dupont Circle restaurant and lounge. Specialties include martinis, caviar, Eastern European beers and, of course, vodka—the list features more than 150 varieties, which the knowledgeable and friendly staff is happy to help you navigate. Order it in a cocktail, as a shot, or on the rocks. Vodka flights, two-ounce pours of six vodkas, are a good way to explore the menu. Weekdays from 5 to 7, all house martinis are half off.
