This freezer-isle ice cream, which had humble beginnings in the 1920s, has been sold in franchised shops since 1976. Small and neat, the unassuming shops are devoid of splashy colors or cartoon characters. Ice cream names are straightforward--Green Tea, Dulce de Leche, Bailey's Irish Cream--but the flavors are sophisticated. The Belgian Chocolate is dark and speckled with bittersweet flecks. There are also thick, creamy shakes and malts.
