Years before they decided to launch Thuyen Vien, Loan and Si, two Vietnamese immigrants, earned a reputation as superb dinner hosts with family and friends who say they were always pleasantly surprised at the couple's creative dishes that spanned every imaginable type of food. Nowadays, that enthusiasm is found daily at their restaurant, where they provide some of Southern California's best vegetarian dishes in a small but clean setting, just blocks from Disneyland. Try the Buddha's Feast: broccoli, bok choy, cabbage, carrots, mushrooms, onions and sautéed tofu in a broth with your choice of soy chicken, soy beef or chow mein. The lemongrass “chicken” or Thai vegetable curry are also tasty. But if you can't decide, ask the friendly owners for advice; after all, they are the ones doing all the cooking.
