Ranging from ¥1,400-1,730 for pork or pasta, Flags Cafe & Dining doesn’t offer the cheapest lunch sets around. But when the price includes a salad bar with unlimited wine, who can complain? The atmosphere is unexpectedly bright and airy for an underground affair, with light wood-grain tables and Roman Holiday permanently paying on the kudzu-crept walls. The main clientele are young women and dating couples; evenings offer more typical à la carte fare.
