Bangkok Diner is a compact 40-seat Thai restaurant in the basement of Otemachi Building, directly connected to Otemachi Station via the underground concourse. The casual, unfussy interior delivers authentic Thai street-food flavors to Tokyo's financial district — from fresh spring rolls and tom yum soup to pad thai, green curry, gapao rice, and the beloved Khao Man Gai steamed chicken. A reliable weekday lunch and dinner destination for nearby office workers; closed on weekends and public holidays.
