Now open as of Friday January 13th is O3 Bistro & Lounge in the former CPK on Van Ness. There are about 45 seats in the contemporary dining room, with a spacious bar and lounge with room for 35 (you can check out photos in their Facebook album). Chef Joseph Villanueva’s (previously at Le Colonial) pan-Asian dinner menu includes braised oxtail tacos with a jicama cabbage slaw in a wonton shell ($9) to larger plates like seared scallops, lobster garlic noodles, baby bok choy, uni XO sauce ($27). Lunch has fried chicken, a burger, and glass noodle salad ($7–$13). Cocktails range from $11–$12, and are made with fresh juices. Hours will be Mon–Wed 11am–11pm and Thu–Sat 11am–2am (kitchen closes at 11pm). A late-night bar menu may launch later. There will also be pre-show service for those attending the symphony and opera house nearby—and it should also be a handy spot for lunch when you’re in the neighborhood to check out City Hall or the Asian Art Museum.

524 Van Ness Ave. at McAllister, 415-934-9800.
