Ikebukuro is known for themed cafes and restaurants, but often the food at these establishments can be a bit of a letdown. Butler Cafe Swallowtail goes against this stereotype by offering delicious pastries and a sumptuous course dinner. The menu changes monthly, so there are always new treats to enjoy from Swallowtail’s chef and patissier. While you sip from fine china, the servers, decked out in three-piece suits, will wait on you. As they have undergone rigorous training to become butlers, you can expect the utmost professionalism. The atmosphere is also beyond the standards expected of a themed cafe, with a chandelier dripping from the ceiling, plush seating covered in brocade fabric, and cozy fireplaces and finely carved grandfather clocks punctuating the walls.
