Long Hai is a Vietnamese restaurant in Tustin. More than merely serving as a neighborhood place, this restaurant’s Vietnamese offerings truly excel, worthy of a strip mall off Magnolia, if not Bolsa itself. The menu is mostly a greatest-hits of Vietnamese food: bún, pho, rice dishes, and Chinese-American favorites for the 10 OC residents who don’t care for the flavors of the Mekong. But Long Hai adds twists. The cha gio aren’t just glistening, dense egg rolls; they come with a platter of herbs so you can make tacos à la bánh xèo. Frog legs don’t just come as sinewy twigs; they’re fat, chewy, dripping with garlic butter and garnished with green onions. Then comes the seafood, gorgeous slabs of fish marinated in sauces ranging from ginger to basil to a tamarind glaze on a fried sole that has long been the stuff of local legend.
