Valencia Market is a cool little Asian market specializing in Korean foods.  Yet they also have some other Asian goods, like tea pots, trinkets, and crafts.  They carry other ethnic foods as well, such as Japanese and Chinese foods.  You can get a variety of spices, sauces, beverages, sweets, noodles, and rices.  Valencia Market has a small meat counter too and deli.  If you don't feel like driving all the way into the valley to get, for instance, kimchi and dumpling wrappers, then this is your place.  This is also a nice place to add some new ingredients to your culinary mix.
