Arteries love a challenge and there are few places to give them one as tasty as at Super Duper. The rising San Francisco burger chain has a new Metreon location to scarf down Niman Ranch grass-fed burgers and crispy, parmesan and garlic beurre blanc fries. Toss in an organic strauss milkshake and call it a day. For those of us whose arteries are in the off-season though, there are other options. Juicy Portobello and Veggie Burgers with hummus are prepared from scratch alongside Super Dupers zesty pickles and tangy jalapenos.
