Perhaps Japan's most popular India-restaurant chain, Maharaja offers good-quality curries and tandoori dishes at reasonable prices. Vegetarian options are available. Set lunches (11am-3pm) start at Y980, and there are various party plans in the evening.
This book will introduce you to more than twenty of Japan's favorite specialty foods that are less well known abroad, along with a guide to the best places in Tokyo to try them and expert tips on what to order. From Bento.com.
