If this were closer to where I live this would be my only go to grocery store. It has EVERYTHING your local chain grocers don't carry and should. Need a rice cooker??? Super G Mart has a few to choose from! If you're looking for shrimp paste they have over 5 countries you can choose which paste you want from. Same with any other product you're taste buds are itching to savor.
Oh and try avoiding weekend trips. It's less crowded and quieter during the week.
