Take a hint from the hungry hoards lining the sidewalk for early morning weekend dim sum—they know what's what. Scrumptious Cantonese, speedy service, and densely packed quarters are how it's done here at Mayflower, one of three locations in the Bay Area. Super fresh seafood is their specialty, so settle into closely spaced banquet tables and dig into steamed surf clams flavored with green onions and soy; or salt- and pepper-crusted shrimp so fresh they still may be quivering. Not in the mood for ocean gems? Roll up your sleeves for an array of meaty bites like steamed buns packed with roasted sweet-and-salty pork; sticky rice noodle rolls stuffed with beef, ginger, cilantro, and splashed with soy; or plump and hearty black sesame dumplings.
