Chinese restaurant Lao Sze Chuan, serving Szechuan favorites in an upscale setting, opened this week at North Bethesda Market near Whole Foods and Seasons 52. The Chicago-based chain will be in direct competition with one of its neighbors, the two-year-old China Garden on Woodglen Drive. This location of Lao Sze Chuan is owned by Gaithersburg-based Ivea Group.
