Back when I was a student at The College of Idaho, I was a regular at Mancino's. They're a hole-in-the-wall kind of restaurant with flimsy tables and cheap plastic table cloths and not really enough space to say there's a dining room (although there's a bit of room to eat).
Their grinders are, however, The Best. There's something about the melted cheese and tomatoes baked in: the messy, eat-over-a-napkin kind of sandwich, that is Oh So Yummy. I can't call myself a regular anymore (that was many years ago), but every once in a while I just have to have a grinder from Mancino's. And when I do get one, they're every bit as good as I remember. I have never been disappointed.
