New Englanders hungry for a lobster roll fix need look no further than this super-friendly spot, where the rolls are utterly authentic and accompanied with slaw and fries. But then this is California. So go for the Dungeness crab roll. The V-shape storefront, which stands on a busy Market Street corner, is all worn wood and paint and comfortably funky. It seems like everyone in the neighborhood turns out for one-dollar West Coast oysters on Tuesday afternoons, all day. A second branch is in Lower Pacific Heights.
