Opéra Garnier, the magnificent and magical former haunt of the Phantom, painter Edgar Degas, and any number of legendary opera stars, still hosts occasional performances of the Opéra de Paris, along with a fuller calendar of dance performances, as the auditorium is the official home of the Ballet de l'Opéra National de Paris. The grandest opera productions are usually mounted at the Opéra de la Bastille, while the Garnier now presents smaller-scale operas such as Mozart's La Clemenza di Tito and Così Fan Tutte. Gorgeous though the Garnier is, its tiara-shape theater means that many seats have limited sight lines, so it's best to ask specifically what the sight lines are when booking (partial view in French is visibilité partielle). Needless to say, the cheaper seats are often those with partial views -- of course, views of Garnier's house could easily wind up being much more spectacular than any sets on stage, so it's not really a loss. Seats go on sale at the box office two weeks before any given show or a month ahead by phone or online; you must go in person to buy the cheapest tickets. Sometimes rush tickets, if available, are offered 15 minutes before a performance. The box office is open 11-6:30 daily. Métro: Opéra.
