Named after the Italian word for "This view will get you lucky" (or "waterfront"... whatever), Lungomare's a sprawling, 120 indoor/80 outdoor-seat cafe-cum-restaurant-cum-bar-cum-date-spot, owned by the chef behind Chop Bar and the two dudes responsible for Grand Cafe.
Jack London Square's Lungomare has a few great things going for it. It serves modern Italian food with that Northern California twist (all of the ingredients are sourced from local producers). The waterfront location has prime seating overlooking JLS and the harbor, which means its views are sublime. The interior is contemporary and classy, and it has a pretty awesome brunch with seasonal frittatas and olive oil cakes. Lungomare is definitely the kind of place you take your parents.
