Tamarine has long been a Palo Alto standby for its refined take on Vietnamese food that doesn’t sacrifice authentic flavor. There’s nearly always a corporate lunch happening in the private dining room, and techies, families and couples alike fill the rest of its linen-topped tables.Family-style sharing of dishes is encouraged, which is good because deciding on just one entrée is nearly impossible. To start, make like the regulars and order one of the “Tamarine Taste” appetizer platters with a round of tropical fruit-infused cocktails. Then move on to the fresh shrimp spring rolls, full of bean sprouts and mint; the springy ginger-chili seitan with steamed coconut rice; and curried long beans, sautéed with fragrant makrut lime leaves and chili.
