Tachibana-san no Mousou Sachi Gohan

Tachibana, a humble office lady living in Kawaguchi City, Saitama Prefecture, enjoys searching for restaurants every night while fantasizing, "If I were to go to dinner with this person, it would be here...!" This is the birth of the first gourmet manga in history (?) where the protagonist doesn't actually eat or go to restaurants.
