Oyster omelette is Taiwan's signature night-market dish — eggs, small oysters and leafy greens bound with sweet potato starch into something closer to a savoury pancake, finished with a sweet-salty red sauce. This shop has been cooking them beside the old Jianguo traffic circle for decades, and rounds the menu out with pork rib soup, oyster soup, clam soup and rice cake. A reliable first stop before the sweets.
