BOO KOO, a Southeast Asian eatery, is perfectly tailored to the downtown Mill Valley set: the menu is predominantly vegan, with optional wild/free-range/ grass-fed protein toppers and locally sourced ingredients comprising the street food–inspired dishes; the draft beer list is lengthy and local; and there’s a kids’ menu. Add the recent expansion and prime location — a busy corner across from the Depot Plaza — and you have a perfect package for hungry Marinites.

The majority of Boo Koo’s offerings are conceptualized and created by the cofounders, husband-and-wife team Matt Holmes and Megan Vinson. Vinson grew up in Lindsay, California, a region known for its agriculture. “I would describe my style and skill set as an untrained but highly enthusiastic home chef gone wild,” she says of her kitchen antics. Despite her humility, Vinson continues to lead her team in creating Northern California–influenced Asian street food. “You are highly unlikely to find wok-seared Brussels sprouts or homemade ginger sodas in the streets of Saigon, but you will find them in Mill Valley,” Vinson says. “We hope to provide a relaxing atmosphere along with an alternative to the town’s menu of burgers and pizza.” Here, Vinson shares her take on bo luc lac, or shaking beef.
