Matsumoto’s Shave Ice (USA). 'Maybe it’s the exotic, homemade flavors such as salty dried plum and coconut cream. Maybe it's the ice cream and azuki beans. Or maybe it’s the history. The building dates to the 1920s, but it wasn’t until 1951 that Japanese immigrant Mamoru Matsumoto opened his grocery here. Shave ice quickly became the best seller when introduced in the 1960s.'
