Food served on slate in Restaurant Life Posted July 23, 2011 It's probably a LOT cheaper to buy and replace. A lot of people might not know this (or maybe a lot do) but nice, hell, even decent, restaurant plates, bowls and cups are EXPENSIVE. Some of them run like, 20-30 dollars per plate. I'm not saying your local Chili's uses this, but a run of the mill "fine dining" plate probably runs at least 30 bucks. Bowls, different shapes, sizes, etc all cost a lot of money. What does a slab of slate cost? 5 bucks? Break one, it's not that big of a deal. Just run down to the Home Depot, lol. I worked at a place that served a salumi plate of slate...it looked nice and actually held the cold temp longer than I think a plate would. I think we did some sort of tartar on it too. Maybe it wasn't slate though, it may have been some sort of other faux something or other. But it looked cool.
