Simple, down-home Vietnamese food prepared extremely well. Their deep-fried ichiba harumaki (market spring rolls) are crunchy and flavorful; other highlights are fried tofu stuffed with beef and an excellent pho noodle soup, listed on the menu as gyuniku udon. They serve 333 and Saigon beers, but don't miss trying a bottle of the eye-opening Chang beer from Thailand. The final bill comes in at a very modest Y2,000-Y2,500 per person.
