Angelenos have the opportunity to sample many global variations of shaved ice — but shaved ice is just so 2010. Nowadays it's all about shaved snow. Taking the concept of shaved ice a step further in its logical evolution, condensed milk — sometimes with a flavor added — is frozen into blocks of ice and then shaved, resulting in a bowlful of silky smooth ribbons. One of the first restaurants in the area to serve shaved snow, Class 302 in Rowland Heights seems perpetually crowded. Waits of a half-hour or longer are the norm, regardless of season or temperature. Yet you won't see many give up their place in line and leave, and with good reason. While many places have jumped on the shaved-snow bandwagon, it's hard to top the small, Taiwanese, schoolhouse-themed restaurant, which features a decor of school desks and chairs and a blackboard menu. You can pick three choices from a variety of toppings or go with set combos, like strawberry or mango-mochi — which is truly worth the wait. 1015 S. Nogales St., #125, Rowland Heights.
