I don’t feel comfortable giving too many specific details, but I have heard things about their food department. It’s very troubling. Let’s just say that their upkeep in their restaurants would raise some concerns with the health department.
I’ve never been hot to eat at SFMM just because of their outrageous prices, but McDonald’s is a beyond excellent value compared to SFMM. At least you’re not usually going to find a rat in there or have no AC, or have a backed up sewage drain close to cooking equipment.
So yeah, I would highly HIGHLY recommend you don’t eat at SFMM. At all. Ever. Don’t even think about it.
