Ttosuni Sundae (또순이원조순대)
Seoul, South Korea
Started as a street stand in 1976, now the anchor restaurant of Sillim-dong Sundae Town. Four decades of sundae-making earned Ttosuni a ground-floor spot in the Wonbilding complex and repeat features on KBS and MBC television. The signature baek sundae (white sundae) comes fried with vegetables. Open 24 hours, which tells you something about demand.
