Fresh fish fans should mark Saturday down on their calendars: That’s the day Sasa opens its doors in Walnut Creek. Billed as the only Izakaya-style (Japanese small plates) restaurant in Contra Costa, Sasa comes comes with some foodie-cred: the executive chef is Philip Yang, the chef/owner of Lafayette’s Blue Gingko, while the 100-year-old former Lawrence Meat Market was restored and renovated by Brian Hirahara, the same developer behind the popular Va de Vi just down the street. Former Va de Vi chef Kelly Degala was also briefly on board as executive chef but was let go by Yang earlier this year (“one too many executive chefs in the kitchen,” according to Degala). As a sushi fan, I’m pretty excited to try out their fresh fish, which the restaurant says it will import daily from Japan’s renowned Tsukiji Fish Market, the largest fish market in the world. There’ll be a full bar too, including an extensive sake and Shochu list—check out their website for more details. Sasa opens this Saturday at 5 p.m. and will be open for lunch and dinner daily after that: Mon.–Sat., 11 a.m.–close, and Sun. 11 a.m.–8 p.m. Sasa, 1432 North Main Street, Walnut Creek,
