Loved it! Friendly, relaxed atmosphere. Very tasty Vietnamese food. The menu is not as extensive and varied as Sunflower, but the dished we tried tonight (tofu spring rolls, curried shrimp, tofu in tomato sauce) were very, very flavorful. Inexpensive. Plentiful.
Whoever posted this restaurant here earlier: Thanks!
It is at 3808 Spicewood Springs Road, just west of MoPac (Loop 1). It has a website.
