The quirky tea-parlor-meets-twilight-zone speakeasy is filled with rows of Asian sweets. Peruse shiny buns filled with sweet potato, coffee-bean cream and red-bean paste. Nibble on vanilla sponge cake, walnut-chocolate squares and sweet green-bean pastries. What's this? Opium cookies? Don't get your hopes up: It's shortbread covered in poppy seeds. Giggling, hopelessly friendly cashiers ring you up, ensuring you walk out the door with your own lopsided grin.
