Last night we had a person send back their lamb because it wasn’t hot.
Today we got a review complaint that their steaks weren’t served hot. 
Fun fact: Most main dishes, especially proteins should not be served piping hot.
There is a reason a chef will tell you to let a steak rest before serving it. It will allow the juices to permeate the cooked meat. It will often continue to cook to its proper temperature.
It truly is an older generations belief that if the food doesn’t burn your mouth then it’s not being served properly.
But it’s simply not true.
Occasionally someone will tell me their order isn’t fresh because it’s not piping hot. I assure each order is made to order. Yes mashed potatoes are cooked and batched but even your French fries are cooked when the order comes into the kitchen.
So don’t be surprised if your meal comes to the table warm.
That’s how it’s supposed to be served.
