I have never been in Mexico during this day….I don’t think. I realize this is a special day in Mexico. Are any businesses closed such as Mega, Walmart, etc ? We arrive early evening on the 5th so just wondering about pick up groceries, etc.
Tres Rios Dia is a fairly significant day and is celebrated much like Christmas. Everything is open. All the stores have massive piles of what I call “King Cakes”. The cakes have a plastic baby baked inside and there is a special significance to getting the piece with the “baby” Maybe someone with a lot more knowledge can fill in the blanks.
