333 Beer can

I'm not able to confidently identify "333 Beer can" as a standard Vietnamese dish or menu item. While 333 is a Vietnamese beer brand, "333 Beer can" as a food item doesn't match any common Vietnamese dishes I'm aware of. Could you provide additional context, such as: What did it look like when served? Any other details from the menu or restaurant? Could it be a nickname or local name for something else? This would help me give you an accurate description rather than guessing.
