Need suggestions for ethnic markets to visit for a college class on international food. Plenty of Asian places (we're near Westminster's Korean and Vietnamese areas) so I need other types (have plenty of Hispanic choices also). Would love some eastern European (Russian?), Middle eastern, African, etc. choices if they exist here. General area is east of 605 fwy, west of 57, south of Imperial Hwy and no farther south than Huntington Beach. Appreciate any and all suggestions.
