Let's do lunch:
Got $3 to spend on lunch? Take a pass on the Cheez-Its and Pepsi from the lunchroom vending machine. SF Weekly food critic Meredith Brody says spend it on a banh mi dac biet (roast pork and paté sandwich) at Saigon Sandwiches (560 Larkin at Eddy).
Serious darts, a decent selection of Anglo-American drafts, Brit-steeped pub grub, and happy-hour beer specials (4-6 p.m.): The Pig and Whistle (2801 Geary at Wood).
Get a taste of Barbary Coast quirkiness in a room that's dim and quietly sleek. Experience it on the cheap via happy hour specials (5-7:30 p.m.) -- 15 Romolo (15 Romolo at Broadway).
