Don those sunglasses as you approach the Rice Box on the Shepherd Curve; its psychedelic-bright, Hong Kong cityscape exterior is dazzling. This food truck, all grown up into a proper and casual restaurant, serves clean, classic Chinese in generously sized paper boxes to take home or unfold onto plates and enjoy on the popular patio. Mongolian beef with fried rice is close to perfection, though the General Tso was a bit sweet and in need of the firepower of a few potent red peppers. The Chow Fun (wide, flat noodles stir-fried with egg and green onion) also proved a little too bland to be fun. Still, we finished happily with egg custard buns, a weird, delightful riff on savory bao.
