Lon bia 333

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 it looked like when served? - Any other details from the menu or restaurant? - Whether it might be a nickname or local name for something else? This would help me give you an accurate description rather than guessing.
