All our brunch suggestions in one handy location. 1319 Rockville Pike, Rockville; 4316 Markham St., Annandale. These two restaurants-the area’s top dim sum destinations-set themselves apart with handmade noodles and dumplings. Rustic, wide strands are as satisfying when slicked in a hot-and-sour sauce as they are submerged in spicy beef-tendon soup, while pork-filled pot stickers are a staple at every table. The rest of the menu is rich in treasures, too, including garlicky cucumbers, Peking-beef wraps, braised pork on rice, and thousand-layer pancakes. Affordable prices make it easy to sample it all.
