Royal Crystal Cafe is a cafe in Ginza, Tokyo that serves afternoon tea, cake, and coffee. The afternoon tea comes with beef stew and egg tarts, and the siphon coffee can be refilled. The basement space holds antique cups, Lalique glasswork, and a Chagall painting, and a reserved private area divided by curtains is also available. Seats fill up on weekday afternoons and weekends, so it is difficult to enter without a reservation.
