There is no too late to eat as in, if you’re hungry and not tired enough to sleep, you’re hungry. And it would depend on when the rest of the meals are eaten, when you wake up, when you go to sleep, what you did before, etc.
but do note that eating after a certain time does slow your metabolism and negatively affect it, so if someone eats late, but is unhappy with their metabolism rate, or wants to lose weight in a healthy way but eats late, and is having trouble losing the weight and with their metabolism, that is definitely contributing and should be kept in mind
