This sauce served at a teriyaki based restaurant and when order a bowl it is already put on the side salad but can be order in a small container separately. I noticed that they have tons of these containers at the front cashier ready to be placed into orders of needed and they are just in a case,not refrigerated or warmed. Just room temperature. Anyways,I took some pics and a video to help anyone who can identify and what the recipe to this could be.
