It's April 28, Super Duper Day, which means that Super Duper Burger is giving away free hamburgers at its seven locations (five of which are in S.F.). The first 100 people in line at each location at 3 p.m. will receive a free mini burger, aka a four-ounce Niman Ranch patty topped with cheese, lettuce, tomato, onions, and Super sauce.
Of course, it'll only run ya a fiver if you happen to be number 101 in line, but we know that's not the point. Free food always tastes better. So go! Super Duper's S.F. locations include Castro (2304 Market), downtown San Francisco (721 Market), Metreon (783 Mission), Embarcadero (98 Mission), and Marina (2201 Chestnut Street).
